feat(cli): v1.7.0 — terminal parity for SSE + members + mentions

Three new verbs that wrap the v1.6.x REST surface:

  claudemesh topic tail <name>  → live SSE consumer with N-message backfill
  claudemesh member list        → mesh roster decorated with online state
  claudemesh notification list  → recent @-mentions of you across topics

Each command auto-mints a 5-minute read-only apikey via the WS
broker and revokes on exit, so users don't manage tokens. SSE
client uses fetch + ReadableStream so the bearer stays in the
Authorization header.
