refactor: replace static guardians with elemental progression system

Replace the old GUARDIANS constant (arbitrary floor assignments) with a proper
elemental → compound → exotic → combo progression:

- Floors 10-70:  Base elements (Fire, Water, Air, Earth, Light, Dark, Death)
- Floor 80:       Utility element (Transference)
- Floors 90-110:  Compound elements (Metal, Sand, Lightning)
- Floors 120-140: Exotic elements (Crystal, Stellar, Void)
- Floor 150+:     Procedural combo guardians (scaling with floor)

Key changes:
- Create guardian-data.ts with BASE_GUARDIANS (14 static entries)
- Simplify guardian-encounters.ts to only handle procedural combos (150+)
- getGuardianForFloor() now generates names for empty-name entries
- Remove old compound/exotic duplicate definitions from guardian-encounters.ts
- Update spire-utils.test.ts to test the new progression
- Update SpireSummaryTab.test.ts floor counts (14 static + 10 combo = 24)

All 89 guardian-related tests pass. 3 pre-existing failures in
room-utils-floor-state.test.ts are unrelated (speed room / floor 0 edge cases).
