hub: ASCII banner, MOTD, ctrl+c→main-menu everywhere, Shell option

Browse source 
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.
