Add view/browse command to render a snapshot's file tree

- New `view <name>` command (alias `browse`) renders the actual backed-up
  file tree from versioned metadata, distinct from `show` (config overview).
- Defaults to the latest snapshot, depth 2, with deeper directories summarized
  by file count; --depth/-d N (0 = full) and --version V override.
- engine/view.rs: load_snapshot + pure build_tree/render_lines (collapse
  single-child chains, file counts); unit-tested.
- DB: latest_version() and version_timestamp(); reuses restore_entries.
- Wiring mirrors run: cmd_view, dispatch, Action::View, actions/view, main.
- README documents view/browse. 48 tests passing.
