Add interactive TUI browsing and reversible cleanup

[MicroMilo]

What changed

• Turn the terminal explorer into a reusable browsing surface with fuzzy search, filters, sibling sorting, local tags, bookmarks, and session-local tabs.
• Keep search and view controls attached to the loaded metadata map, with clear UI state and help text.
• Add an approval-gated cleanup loop: dd stages an exact path, the coding agent advises from metadata, and only an explicit confirmation moves it to system Trash with undo support.
• Add path actions, workspace persistence, bounded deep relationship analysis, file previews, and privacy documentation.
• Add deterministic tests for cleanup, workspace actions, tags, fuzzy browsing, sorting, and tabs.

Why

The TUI should be a continuing local workspace rather than a one-time directory listing. The new controls let a user narrow and organize a path while keeping the scan read-only by default and making cleanup reversible.

Privacy and safety

• Reports stay metadata-first and redacted by default.
• Search, filters, tags, and tabs do not upload data or read unopened file contents.
• Local tags, bookmarks, recents, workspace state, and cleanup history stay in the local Clean Your Data state directory.
• Cleanup is limited to an exact, measured, user-confirmed path moved to system Trash; app-managed, cloud-sync, unknown, home, and root paths remain blocked.
