- pact-utils.ts: Replace GUARDIANS[floor] with getGuardianForFloor() so pact multipliers work for extended guardians (floors 110+)
- SpireSummaryTab.tsx: Use getGuardianForFloor()/getAllGuardianFloors() instead of static GUARDIANS constant; update type annotations to GuardianDef
- PactDebug.tsx: Use unified guardian lookup; add null guards for getGuardianForFloor return type
- PactDebugSection.tsx: Use unified guardian lookup; add null guards for getGuardianForFloor return type
