fix: complete golemancy component-based redesign cleanup

- Fix summonGolemsForRoom to use golemLoadout instead of removed enabledGolems
- Fix discBonus hardcoded to 0 in golem-combat.ts pipeline (now computed from discipline effects)
- Remove deprecated types: SummonedGolem, ActiveGolem, GolemDef
- Remove legacy GolemancyState fields: enabledGolems, summonedGolems, legacyActiveGolems
- Remove orphaned store actions: toggleGolem, setEnabledGolems
- Delete orphaned legacy data files: base-golems.ts, elemental-golems.ts, hybrid-golems.ts
- Update GolemDebugSection to use new golemLoadout system
- Update golemancy-spec.md §17 to reflect all features as complete
- Update all test files to match new type shapes
- All 958 tests passing
