fix: multiple bug fixes - infinite loop crash, enchant tick handlers, discipline crash, Plasma symbol, desync

- #236: Fix Climb the Spire React #185 infinite loop - removed redundant set() in processCombatTick that caused double Zustand writes per tick
- #235: Add enchanting design/prepare/apply tick handlers - extracted to pipelines/enchanting-tick.ts
- #235: Fix startApplying not setting currentAction to 'enchant'
- #243: Guard discipline store against undefined activeIds/processedPerks from corrupted persisted state
- #245: Change Plasma symbol from ⚡ (conflicts with Lightning) to 🔴
- #241: Fix combat store maxFloorReached desync - initialize to 0, reset on exitSpireMode
- #239: Fix EffectSelector not rendering when unlockedEffects is empty (fresh game)
- Created pipelines/enchanting-tick.ts to keep gameStore.ts under 400 lines
