Refresh workspace-changes status item on turn end and patch updates

`request_status_line_workspace_changes_refresh` was defined but never
invoked, so the `+added/-deleted ?untracked` segment cached the first
lookup and stayed frozen for the rest of the session. Hook it into the
same refresh paths that already refresh branch and git-summary state:

- both `finalize_turn` sites in `turn_runtime.rs` (so user-visible turn
  end picks up edits codex applied during the turn), and
- `on_turn_diff` in `protocol_requests.rs` (so mid-turn patch applies
  immediately refresh the stats without waiting for the turn to finish).
