Vault list was stored only in React useState, lost on every app restart
or update. Now persisted to ~/.config/com.laputa.app/vaults.json via
Rust backend commands (load_vault_list, save_vault_list).
- Add vault_list.rs module with VaultEntry/VaultList types and JSON I/O
- Register load_vault_list/save_vault_list Tauri commands
- Extract vaultListStore.ts utility for frontend persistence calls
- Rewrite useVaultSwitcher to load on mount and persist on change
- Show unavailable vaults greyed out with warning icon instead of
silently removing them
- Add mock handlers for browser/test environments
- Add useVaultSwitcher tests covering persistence, availability, dedup

The vault path was stored only in React state (useState), which resets
on every app restart. Now the last active vault path is written to
~/Library/Application Support/com.laputa.app/last-vault.txt on every
vault switch, and loaded on startup. If the saved vault no longer exists,
the existing onboarding flow shows the vault picker instead of silently
falling back to the demo vault.
