fix: add error logging, missing persist fields, and version to store configs

- safe-persist.ts: add console.error logging to setItem catch block (was silently swallowing all errors)
- manaStore.ts: add meditateTicks to partialize (was lost on refresh)
- combatStore.ts: add currentAction, currentRoom, comboHitCount, floorHitCount, totalSpellsCast, totalDamageDealt, totalCraftsCompleted to partialize
- All 8 stores: add version: 1 to persist configs for future schema migration safety

Fixes #147
