feat(cli): add --resume and --continue flags to launch

claudemesh launch now supports:
  --resume <id> / -r  — resume a previous Claude Code session
  --continue / -c     — continue the most recent conversation

When resuming, skips generating a new session ID so the mesh peer
identity persists. The detectClaudeSessionId() fallback in ws/client.ts
picks up the existing session UUID from the .jsonl file.
