Merge origin/main into agent/1de295a0da42

Resolves conflict in main_menu.gd's play button: kept this branch's real
world_list.tscn transition over main's stale TODO placeholder (main's
version predates this fix; nothing else has touched the play button
since). Brings in PR #37's /auth/refresh endpoint and its tests cleanly,
no other conflicts.
