feat(phantom-ship): hara-gmail-mcp server (path 1, IMAP+SMTP) 📬

Adds an MCP server exposing read tools (list_inbox, search, read_email)
across three personal Gmail accounts using existing app passwords in
/etc/openclaw/. Wired into claude-channels via --mcp-config. Slated for
replacement by an OAuth2 Gmail+Calendar server in path 2.
