feat(cli): add --vault option for daemon and mirror commands

Allow specifying a separate vault directory for .md files, decoupled from
the database directory (where PouchDB data lives).

- Add --vault/-V flag to CLI options parser
- Use vaultPath (or fallback to databasePath) for file system operations
- Works with both daemon and mirror commands
- Log vault path alongside database path at startup
