Major improvements to the Field of View (FOV) system:
1. Added thread safety with mutex protection
- Added mutable std::mutex fov_mutex to UIGrid class
- Protected computeFOV() and isInFOV() with lock_guard
- Minimal overhead for current single-threaded operation
- Ready for future multi-threading requirements
2. Enhanced compute_fov() API to return visible cells
- Changed return type from void to List[Tuple[int, int, bool, bool]]
- Returns (x, y, visible, discovered) for all visible cells
- Maintains backward compatibility by still updating internal FOV state
- Allows FOV queries without affecting entity states
3. Fixed Part 4 tutorial visibility rendering
- Added required entity.update_visibility() calls after compute_fov()
- Fixed black grid issue in perspective rendering
- Updated hallway generation to use L-shaped corridors
The architecture now properly separates concerns while maintaining
performance and preparing for future enhancements. Each entity can
have independent FOV calculations without race conditions.
