Add ability to remove vaults from the app list without deleting files on disk,
and restore the bundled Getting Started demo vault when needed.
Changes:
- Rust: add hidden_defaults field to VaultList for tracking removed default vaults
- useVaultSwitcher: add removeVault() and restoreGettingStarted() with auto-switch
- useCommandRegistry: add 'Remove Vault from List' and 'Restore Getting Started Vault' commands
- StatusBar: add X button per vault item in vault menu dropdown
- 25 new tests covering removal, restore, edge cases, and command palette

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
