UX pass on the single-login hub:
- ctrl+c now always returns to the main menu from any in-hub plugin/game
instead of being forwarded. Fixes the snake game being un-exitable (it never
handled ctrl+c) and makes "back to menu" uniform across every screen.
- profullstack.com ASCII banner rendered atop the hub menu and the join@
onboarding flow.
- MOTD box under the title (guest vs member tailored; AGENTBBS_MOTD overrides
the body).
- New "Shell" hub entry drops straight into `bash -l` in the member's pod; the
existing "Pod" entry now attaches to the pod's main session.
- Polish: highlighted selection + ❯ cursor, brand colors, clearer footer.
