Pull request overview

This PR merges submission-ready changes from the release/submission-1 branch into develop. The changes prepare the codebase for submission by removing unnecessary development files, adjusting key bindings for campus environment compatibility, improving memory safety, and refining numerical precision handling for normalized vector validation.

Changes:

• Removed development-only files (debug utilities, documentation, test scenes) to create a clean submission package
• Updated key bindings from +/- to P/M for FOV, brightness, and diameter adjustments to accommodate campus keyboard layouts
• Enhanced memory safety by improving free_scene function to use double pointers and properly set pointers to NULL after freeing
• Introduced NORM_EPSILON (1e-3) for normalized vector validation to handle real-world input precision while maintaining EPSILON (1e-6) for internal ray tracing calculations
