feat(new-setup-2): phase-2 setup skill + --no-cli-bonus flag

New /new-setup-2 skill, invoked when the user picks "continue setup"
at the end of /new-setup. Linear rollthrough; every step skippable:

  1. What should the agent call you?
  2. What's your agent's name?
  3. Messaging channel (plain list, no AskUserQuestion) — invokes the
     matching /add-<channel> skill, captures platform IDs from its
     output, then wires via init-first-agent.ts with --no-cli-bonus.
     On success, emits the encouragement line verbatim.
  4. Quality-of-life picks (dashboard, compact, karpathy-wiki, plus
     macos-statusbar only when the probe reports PLATFORM=darwin).
  5. Wrap-up.

scripts/init-first-agent.ts gains a --no-cli-bonus flag. In DM mode,
the bonus "wire new agent to CLI" call is skipped when set. Used by
/new-setup-2 so the throwaway CLI-only agent from /new-setup retains
clean single-agent ownership of CLI routing instead of being duelled
by the real agent on the same channel.
