feat: add enchanter disciplines to unlock enchantment effects via perk progression

- Add unlocksEffects field to DisciplinePerk type
- Add unlockEffects action to crafting store (deduplicating merge)
- Modify discipline processTick to detect perk thresholds and return unlocked effect IDs
- Wire gameStore tick to pass unlocked effects to crafting store
- Create 8 new enchanter disciplines with tiered effect unlocks:
  Basic/Advanced Weapon, Utility, Mana, Basic/Intermediate/Advanced Spell, Special
- Higher-tier disciplines require prerequisite disciplines
- Add processedPerks tracking to prevent duplicate unlocks
- Split enchanter disciplines into modular files (enchanter, enchanter-utility, enchanter-spells, enchanter-special)
- All tests pass (784/784), no new TS errors, all files under 400 lines
