feat(setup): clarify setup flow from user-feedback session

- Container step: duration hint + 3-line rolling output window with
  60s stall detector that offers "keep waiting" vs "ask Claude"
- First chat: reframed as a try-out with sandbox-model explainer
  (wakes on message, sleeps when idle, context persists)
- Timezone: auto-detected non-UTC zones now get an explicit
  confirm from the user instead of silent persist
- Outro: added always-on warning + prominent "check your DM" banner
  when a channel was configured; directive last line
- Discord: always show token-location reminder even when user says
  they have one; new "do you have a server?" branch walks through
  server creation if not
- All select prompts: custom brightSelect renderer keeps inactive
  option labels at full brightness (was dim gray); adds @clack/core
  as a direct dep
