feat(cli): 1.31.4 — peer list shows profile.role and groups

claudemesh peer list now surfaces each peer's profile-level role
(set via claudemesh profile) and any joined groups inline next to
the display name, e.g.

  ● mou [role:lead, @flexicar:reviewer, @oncall] (ai) · 0d215762…

When both are empty, an explicit footer is added so absence is
unambiguous:

  ● peer [...]
     role: (none)  groups: (none)

JSON output is unchanged — the broker has been returning profile
and groups all along, only the human renderer was missing the role.

+## 1.31.4 (2026-05-04) — peer list shows roles and groups
+
+`claudemesh peer list` now surfaces each peer's profile-level role
+(`claudemesh profile`) and any joined groups inline next to the
+display name, e.g.
+
+```
+● mou [role:lead, @flexicar:reviewer, @oncall] (ai, claude-code) · 0d215762…
+   cwd: /Users/agutierrez/Desktop/claudemesh
+```
+
+When both role and groups are empty, an explicit footer is added so
+absence is unambiguous instead of looking like the CLI is hiding the
+field:
+
+```
+● peer [...]
+   role: (none)  groups: (none)
+```
+
+JSON output is unchanged (the broker has surfaced these fields all
+along) — only the human renderer was missing them.
