feat(cli): 1.31.5 — JSON peer list lifts role to top level + skill renders it

After 1.31.4 the human renderer surfaced role and groups, but launched-
session LLMs still dropped them when they called peer list --json and
built their own tables.

- Top-level role field. The broker returns role nested under
  profile.role; the CLI now lifts it to a top-level role field at
  parse time so it is the second-most-visible JSON field after
  displayName. profile.role is preserved.
- Updated claudemesh skill SKILL.md peer-list section with the full
  JSON shape (memberPubkey, sessionId, role, profile, isSelf,
  isThisSession) plus explicit guidance to render role + groups in
  any peer table inside a launched session.
