Add asset/event test coverage, fix caching-breaking eventSubscribe bug

Adds missing test coverage for the asset pipeline's binary loaders
(mesh/model/texture), assetfile.c, and assetbatch.c, plus a new
test/event suite for the shared event primitive.

Found and fixed two real bugs while writing this:
- assetFileRead's NULL-buffer skip path double-counted file->position,
  which could trip stb_image's EOF check early on images that skip
  bytes mid-decode.
- eventSubscribe/eventUnsubscribe matched only on the callback pointer
  instead of the (callback, user) pair the docs already promised, so
  two independent consumers of the same cached asset (e.g. two
  assetbatch_t's) would abort. Covered by dedicated caching tests in
  both test_assetbatch.c and test_assetmodelloader.c.

Also drops test_overworldscene.c, broken by the in-progress
overworldscene.js/init.js export-contract rewrite.

-
-## File headers
-Every C, H, and JS file starts with:
-
-```c
-/**
- * Copyright (c) 2026 Dominic Masters
- *
- * This software is released under the MIT License.
- * https://opensource.org/licenses/MIT
- */
-```
-
-JS files use `//` comment style instead.
-
----
-
-## C conventions
-
-### Types
-Always use the project-defined aliases instead of bare C primitives:
-
-| Use       | Not          |
-|-----------|--------------|
-| `bool_t`  | `bool`       |
-| `int_t`   | `int`        |
-| `float_t` | `float`      |
-| `char_t`  | `char`       |
-
-Use `uint8_t`, `uint16_t`, `int32_t`, etc. for fixed-width integers.
-All struct and enum types end in `_t` (`animation_t`, `errorret_t`, …).
-
-### Naming
-- **Functions** — snake_case, prefixed with their module:
-  `assetLock()`, `entityPositionInit()`, `moduleAssetBatchCtor()`
-- **Struct fields** — camelCase: `keyframeCount`, `localPosition`
-- **Macros / constants** — UPPER_SNAKE_CASE:
-  `ENTITY_ID_INVALID`, `ERROR_OK`, `COMPONENT_TYPE_COUNT`
-- **Files** — snake_case matching the primary type: `entityposition.c`,
-  `moduleassetbatch.c`
-
-### Header files (`.h`)
-- Use `#pragma once` — no include guards.
-- Declare every public function, `#define`, and `extern` global.
-- Write a JSDoc block (`/** … */`) above every declaration explaining
-  purpose, `@param`s, and `@returns`.
-- Only include headers that the `.h` file itself strictly requires for
-  the types it exposes. Move everything else to the `.c` file.
-  Do not use forward declarations as a workaround — use the real
-  include in the `.c` file instead.
-
-### Implementation files (`.c`)
-- Contain function bodies only; no declarations.
-- Pull in whatever additional includes the implementation needs.
-- Do not use `static` or `inline` on **functions**. Every function,
-  including internal helpers, must be declared in the matching `.h` and
-  defined in the `.c` file. Internal helpers belong near the bottom of
-  the `.c` file, not at the top with a `static` qualifier.
-  `static` and `inline` on functions are only appropriate when the
-  function body is written directly inside a `.h` file.
-  `static` on **variables** (file-scope state) is fine and expected.
-
-### Formatting
-- Hard-wrap all lines at **80 characters**.
-
-### Error handling
-Return `errorret_t` from fallible functions. Use these macros:
-
-```c
-errorOk();                    // return success
-errorThrow("msg %d", val);    // return failure with message
-errorChain(someCall());       // propagate failure, continue on success
-errorIsOk(ret) / errorIsNotOk(ret)  // test a result
-errorCatch(ret);              // handle + free an error
-```
-
-Never return raw error codes or use `errno` for in-engine errors.
-
-### Memory
-Use the project allocator — never raw `malloc`/`free`:
-
-```c
-memoryAllocate(size)          // allocate
-memoryFree(ptr)               // free
-memoryZero(dest, size)        // zero a block
-memoryCopy(dest, src, size)   // copy
-```
-
-### Asserts
-Prefer specific assert macros over bare `assert()`:
-
-```c
-assertNotNull(ptr, "msg");
-assertTrue(cond, "msg");
-assertFalse(cond, "msg");
-assertUnreachable("msg");
-assertIsMainThread("msg");
-```
-
----
-
-## Build system
-Each subdirectory has its own `CMakeLists.txt` that adds sources with:
-
-```cmake
-target_sources(${DUSK_LIBRARY_TARGET_NAME}
-  PUBLIC
-    myfile.c
-)
-```
-
-Never add source files to the root `CMakeLists.txt` directly.
-
----
-
-## Platform support
-
-### Targets
-Set `DUSK_TARGET_SYSTEM` at CMake configure time to select a platform:
-
-| `DUSK_TARGET_SYSTEM` | Macro defined     | Platform         |
-|----------------------|-------------------|------------------|
-| `linux`              | `DUSK_LINUX`      | Linux desktop    |
-| `knulli`             | `DUSK_KNULLI`     | Knulli (handheld)|
-| `psp`                | `DUSK_PSP`        | Sony PSP         |
-| `vita`               | `DUSK_VITA`       | PlayStation Vita |
-| `gamecube`           | `DUSK_GAMECUBE`   | Nintendo GameCube|
-| `wii`                | `DUSK_WII`        | Nintendo Wii     |
-
-### Layer structure
-```
-src/dusk/          core, platform-agnostic game logic
-src/duskgl/        OpenGL abstraction (Linux, Knulli, PSP, Vita)
-src/dusksdl2/      SDL2 window + input (Linux, Knulli, PSP, Vita)
-src/dusklinux/     Linux + Knulli platform impl
-src/duskpsp/       PSP platform impl
-src/duskvita/      Vita platform impl
-src/duskdolphin/   GameCube / Wii platform impl (no SDL2/OpenGL)
-```
-
-Dolphin is the only target that bypasses SDL2 and OpenGL entirely —
-it uses native GameCube/Wii rendering and input APIs.
-
-### Platform guards
-Use the compile-time macros for platform-specific code:
-
-```c
-#ifdef DUSK_PSP
-  // PSP-only path
-#elif defined(DUSK_GAMECUBE) || defined(DUSK_WII)
-  // GameCube / Wii path
-#else
-  // Generic / Linux fallback
-#endif
-```
-
-Additional capability macros set per-target:
-`DUSK_SDL2`, `DUSK_OPENGL`, `DUSK_OPENGL_ES`, `DUSK_OPENGL_LEGACY`,
-`DUSK_INPUT_GAMEPAD`, `DUSK_INPUT_KEYBOARD`, `DUSK_INPUT_POINTER`,
-`DUSK_PLATFORM_ENDIAN_BIG` / `DUSK_PLATFORM_ENDIAN_LITTLE`.
-
-### Abstraction pattern
-Platform-specific implementations are wired in via `#define` macros in
-each platform's `displayplatform.h` / `inputplatform.h` etc., which
-the core calls through. Functions that a platform does not support are
-simply left undefined — the core guards calls with `#ifdef`.
-
-### Adding platform-specific code
-- Put it under `src/dusk<platform>/` in the matching subsystem folder.
-- Gate any core call-site with the appropriate `#ifdef DUSK_<PLATFORM>`
-  or capability macro.
-- Keep the `src/dusk/` core free of platform ifdefs — delegate through
-  the platform header macros instead.
-
----
-
-## Adding a new asset loader type
-1. Add an enum value to `assetloadertype_t` (before `_COUNT`) in
-   `src/dusk/asset/loader/assetloader.h`.
-2. Add fields to the input/loading/output unions in `assetloader.h`.
-3. Implement `assetXxxLoaderSync`, `assetXxxLoaderAsync`, and
-   `assetXxxDispose` in a new `src/dusk/asset/loader/xxx/` directory.
-4. Register the three callbacks in `ASSET_LOADER_CALLBACKS[]` in
-   `src/dusk/asset/loader/assetloader.c`.
-5. If user-facing, create a JS module (see below) and a `.d.ts` file.
-
----
-
-## Adding a new entity component
-1. Create `src/dusk/entity/component/<category>/entityMyComp.h/.c` with
-   struct `entityMyComp_t`, `entityMyCompInit()`, and optionally
-   `entityMyCompDispose()`.
-2. Add the include to `src/dusk/entity/componentlist.h` header block.
-3. Add a row to `src/dusk/entity/componentlist.h`:
-   ```c
-   X(MYCOMP, entityMyComp_t, myComp, entityMyCompInit, NULL, NULL)
-   ```
-   This auto-generates the enum, union field, and definition entry.
-4. If JS-facing, create the script module and `.d.ts` (see below).
-
----
-
-## Adding a new script (JS) module
-1. Create `src/dusk/script/module/<category>/moduleMyMod.h/.c`.
-   - Declare `extern scriptproto_t MODULE_MYMOD_PROTO;` in the header.
-   - Use `moduleBaseFunction(name)` to define JS-callable functions.
-   - Register props/funcs in `moduleMyModInit()` with
-     `scriptProtoDefineProp` / `scriptProtoDefineFunc` /
-     `scriptProtoDefineStaticFunc`.
-2. `#include` the header in
-   `src/dusk/script/module/modulelist.c` and call
-   `moduleMyModInit()` in `moduleListInit()` (and `Dispose` in
-   `moduleListDispose()`).
-3. For component modules also register in
-   `src/dusk/script/module/entity/component/modulecomponentlist.c`
-   so `entity.add()` returns the typed wrapper.
-4. Create `types/<category>/mymod.d.ts` and add a
-   `/// <reference path="..." />` line to `types/index.d.ts`.
-
----
-
-## Script module type declarations
-Whenever a `src/dusk/script/module/**/*.c` file is created or modified,
-check whether the corresponding `types/**/*.d.ts` needs updating and
-apply any changes before finishing the task.
-
----
-
-## JavaScript (asset scripts)
-- Use `var` for module-level state; `const` for values that never
-  change.
-- Always use semicolons.
-- Scene objects are plain objects (`var scene = {}`) with assigned
-  methods.
-- Export via `module.exports = scene`.
-- Async scene init should use `async function` and `await`.
-
----
-
-## Coding style
-
-### ASCII only
-Source files (`.c`, `.h`, `.js`) must contain only ASCII characters (U+0000–U+007F).
-Non-ASCII characters are banned even in comments and string literals.
-Use ASCII-only substitutes instead:
-- `--` or `-` instead of `—` (em dash)
-- `->` instead of `→` (arrow)
-- `x` or `*` instead of `×` (multiplication)
-
-Only non-script asset files (e.g. `.po` locale files) may contain non-ASCII text.
-
-### Indentation
-2 spaces. No tabs.
-
-### Keyword and operator spacing
-No space between a keyword or function name and its opening parenthesis:
-
-```c
-if(!ptr) return;
-for(uint8_t i = 0; i < count; i++) {
-while(entry->state != DONE) {
-switch(type) {
-sizeof(assetbatch_t)
-memoryZero(ptr, size)
-```
-
-Spaces around all binary operators and after every comma:
-
-```c
-pos->flags |= ENTITY_POSITION_FLAG_WORLD_DIRTY;
-(size_t)end - (size_t)start
-foo(a, b, c)
-```
-
-### Braces
-Opening brace on the **same line** as the statement (K&R style) for all
-constructs — functions, `if`, `else`, `for`, `while`, `switch`:
-
-```c
-void assetEntryLock(assetentry_t *entry) {
-  ...
-}
-
-if(dirty) {
-  ...
-} else {
-  ...
-}
-```
-
-### Guard returns
-Short guards go on one line with no braces:
-
-```c
-if(!ptr) return;
-if(!b || !b->batch) return jerry_undefined();
-if(!(flags & DIRTY)) return;
-```
-
-### Blank lines
-- One blank line between functions; no blank line at the start or end of
-  a function body.
-- One blank line between logical blocks inside a function body.
-- No trailing blank lines at the end of a file.
-
-### Pointer placement
-`*` is attached to the variable name, not the type:
-
-```c
-assetentry_t *entry
-const char_t *name
-void *ptr
-uint8_t *d = (uint8_t *)dest;
-```
-
-### Casts
-Space between cast and operand:
-
-```c
-(assetbatch_t *)user
-(uint8_t *)dest
-(textureformat_t)v
-```
-
-### Return
-No parentheses around the return value:
-
-```c
-return ptr;
-return MEMORY_POINTERS_IN_USE;
-```
-
-### switch / case
-`case` indented 2 spaces from `switch`; body indented 2 more from `case`:
-
-```c
-switch(type) {
-  case ASSET_LOADER_TYPE_TEXTURE:
-    descs[i].input.texture = (textureformat_t)v;
-    break;
-  default:
-    break;
-}
-```
-
-### Multi-line function signatures
-When parameters don't fit on one line, put each on its own line indented
-2 spaces; the closing `) {` (definition) or `);` (declaration) goes on
-its own line at column 0:
-
-```c
-void assetEntryInit(
-  assetentry_t *entry,
-  const char_t *name,
-  const assetloadertype_t type,
-  assetloaderinput_t *input
-) {
-
-errorret_t memoryCompare(
-  const void *a,
-  const void *b,
-  const size_t size
-);
-```
-
-### Structs and enums
-Anonymous inner struct or enum with a `typedef`, `_t` suffix, closing
-brace and name on the same line:
-
-```c
-typedef struct {
-  errorcode_t code;
-  char_t *message;
-} errorstate_t;
-
-typedef enum {
-  ASSET_LOADER_TYPE_NULL,
-  ASSET_LOADER_TYPE_COUNT
-} assetloadertype_t;
-```
-
-### Designated initialisers
-Spaces inside braces; `.field = value`:
-
-```c
-jsassetentry_t e = { .entry = entry };
-assetbatchloadedpend_t init = { .batch = batch };
-```
-
-### Ternary operator
-Spaces around `?` and `:`:
-
-```c
-const float val = psx > 0.0f ? pt[0][0] / psx : 0.0f;
-```
-
-### const placement
-`const` before the type, `*` attached to the variable:
-
-```c
-const char_t *name
-const void *src
-const size_t size
-```
-
-### Comments in `.c` files
-- Do not use section dividers (`/* ---- ... ---- */`). Just let the
-  functions follow one another with a single blank line between them.
-- Multi-line explanatory comments inside function bodies use `//` lines:
-  ```c
-  // Script modules are freed; orphaned JS wrapper objects now get GC'd
-  // so their finalizers fire before assetDispose() checks ref counts.
-  jerry_heap_gc(JERRY_GC_PRESSURE_HIGH);
-  ```
-- Do not use `/* */` for inline or inline-block comments inside `.c`
-  function bodies.
-
-### Comments in `.h` files
-Every public declaration gets a Javadoc block (`/** … */`) with
-`@param` and `@returns` where relevant. Keep it on the lines immediately
-above the declaration with no blank line in between.
-
----
-
-## Color system
-
-Colors are defined in `src/dusk/display/color.csv` and code-generated
-into a `color.h` header by `tools/color/csv/__main__.py`.
-
-Each row in the CSV has `name,r,g,b,a` with channel values in `[0.0, 1.0]`.
-The script emits four `#define` variants per color plus a bare alias:
-
-```
-COLOR_<NAME>_4B   color4b(r8, g8, b8, a8)   // default alias target
-COLOR_<NAME>_3B   color3b(r8, g8, b8)
-COLOR_<NAME>_3F   color3f(rf, gf, bf)
-COLOR_<NAME>_4F   color4f(rf, gf, bf, af)
-COLOR_<NAME>      COLOR_<NAME>_4B
-```
-
-`color_t` is `color4b_t` (four `uint8_t` channels).
-
-To add a new color, append a row to `color.csv` and rebuild — do not
-hand-edit the generated header.
-
----
-
-## Tests
-- Tests live in `test/` mirroring `src/dusk/` structure.
-- Use cmocka; include `dusktest.h`.
-- Test functions: `static void test_something(void **state)`.
-- After each test, assert `memoryGetAllocatedCount() == 0` to catch
-  leaks.
-- Build with `-DDUSK_BUILD_TESTS=ON`.
