feat: unify guardian system — merge static GUARDIANS with extended procedural guardians in Pacts tab

- guardian-encounters.ts: add getGuardianForFloor() and getAllGuardianFloors()
  unified lookup functions that merge static GUARDIANS (floors 10-100) with
  extended system (compound 110, exotic 120-140, combo 150+)
- GuardianPactsTab.tsx: use unified system, update tiers to cover all floors
  (Early 10-40, Mid 50-80, Late 90-100, Compound 110, Exotic 120-140,
  Transcendent 150+)
- guardian-pacts-components.tsx: handle combo guardians with dual-element
  display (symbols + names + '✦ Combo' badge)
- docs/circular-deps.txt, docs/dependency-graph.json: auto-generated updates
- craftingStore.ts: extract initial equipment instances to crafting-initial-state.ts
