- Introduced contentHelpers for table and room template lookups.
- Created level1Rooms.ts with various room templates for level 1.
- Added level1Tables.ts containing encounter tables for animals, martial, dogs, people, fungal, guards, workers, and room types.
- Implemented room generation functions in rooms.ts to create rooms based on templates and tables.
- Added tests for room generation logic in rooms.test.ts to ensure correct functionality.
