- Added enemy naming system with getEnemyName() function
- Updated EnemyState type to include name field
- Updated generateSwarmEnemies() and generateFloorState() to assign enemy names
- Fixed SpireTab.tsx (both versions) to display:

  - Named enemies based on element and floor tier
  - Special floor properties (armor %, dodge chance)
  - Multiple enemies for swarm floors with individual HP bars
- Added ROOM_TYPE_LABELS to constants for display
- Verified floor type generation logic works correctly
- Build succeeds with npm run build
