fix: MSVC ABI, heap allocator, deferred timer - vanillafixes compat

- Restore MSVC ABI (was accidentally GNU since v0.6.0, broke .CRT section)
- Replace game allocator with Windows process heap for filecache and
  libdeflate malloc/free - game allocator not initialized during DllMain
  when injected via CreateRemoteThread
- Defer timer calibration (Sleep 500ms) to lateInit - blocks under
  loader lock during DllMain
- Remove exported malloc/free symbols from DLL
- Eliminate addObject compilation units for SSE files - direct @import
  with AVX target instead
- Heap-allocate filecache (was 9.3MB static BSS)
- Strip transform44 of performance/ externs, pure profiling only
- Rename performance/ to weirdperformance/ to match module convention
- Skip default-off modules in all-variants build step
- Remove dead debug vars and stride logging from particle_sse
