- Cast Variant to String via str() before passing to _on_room_change
- Clear _current_room_id on null room transition (fixes re-entry skip)
- Add push_error for failed dir creation and file writes in _save_report
- Fix docstring: tests/gauntlet-stats.json → user://dev/gauntlet-stats.json
- Namespace stats path to user://dev/ to avoid save data collision
- Replace print() with push_warning in _save_report (codebase consistency)
- Downgrade client-only wire guard from push_warning to silent return

GauntletHUD in UILayer shows TIMER: MM:SS (PB: MM:SS). Timer starts on
room entry, resets on room change, records personal bests to
user://gauntlet-stats.json. Session summary printed on disconnect.
Hidden in non-gauntlet mode (anti-tedium guard).
Adds room_id and gauntlet_mode fields to GameState, parsed from
ObserverSnapshot. Main.gd wires update_from_state() and finalize().
