feat(claude): advisor tool support, per session and as an App Settings default

Claude Code's advisor tool (code.claude.com/docs/en/advisor) lets the session's
main model consult a second, stronger model at decision points: before
committing to an approach, on a recurring error, and before declaring a task
done. Codeman can now start claude sessions with one.

- `advisorModel` field on POST /api/sessions, /api/quick-start and
  /api/ralph-loop/start (fable, opus, sonnet or a full model id in those
  families; haiku cannot advise and is refused). Stored on the session and
  persisted, so respawn, boot restore and reboot restore keep it. Remote and
  docker quick-starts refuse it, as they refuse effort.
- App Settings, Models, "Advisor" segment (Default / Sonnet / Opus / Fable),
  synced as `claudeAdvisorModel`. Run, resume and the Ralph wizard send it.
  Default sends nothing, leaving the CLI's own /advisor choice in charge.
- Carried as the `advisorModel` key in the launch's single --settings JSON,
  merged with ultracode and the statusLine exporter, never the --advisor
  flag: `claude --advisor haiku` exits 1 at launch, which would leave a dead
  pane on every respawn, while the settings key degrades to no advisor. A
  launch without an advisor is byte-identical to before.
