Port the duskscript language into the engine as src/dusk/script + duskscriptcc

Brings over the duskscript VM and compiler from dusk-vm: the runtime (core/vm) lives under src/dusk/script, gated by DUSK_SCRIPT and wired into the engine lifecycle with print()/consolePrint() routed to the console; the standalone duskscriptcc compiler stays a lean host tool (linux/knulli only). Collapses int/fixed/bignum into a single float-backed SCRIPT_VALUE_NUMBER throughout the lexer, compiler, bytecode format and VM, removing the old int16-rollover fast paths and the type-conversion builtins they needed. Fixes a real big-endian bug in the bytecode's 32-bit number reader (found while adding GameCube/Wii endian support via util/endian.h) and converts src/dusk/script and duskscriptcc to dusk's memory/string/assert utilities, which surfaced two more latent bugs: a conservative GC stack scan reading its own local variable's address, and an uninitialized path buffer in scriptReadScript when the caller path has no directory component.
