scawful 2b11338e20 Update version to 0.3.2 and enhance stability across platforms
- Bump project version to 0.3.2 in CMakeLists.txt, vcpkg.json, and relevant headers.
- Increase Windows stack size to 8MB to prevent stack overflow during asset loading.
- Isolate development utilities from CI builds to ensure cleaner release artifacts.
- Implement comprehensive bounds checking and fix segmentation faults in the graphics system.
- Update documentation to reflect new build instructions and stability improvements.
