+### 14) Gateway runtime + port diagnostics
 Doctor inspects the daemon runtime (PID, last exit status) and warns when the
 service is installed but not actually running. It also checks for port collisions
 on the gateway port (default `18789`) and reports likely causes (gateway already
 running, SSH tunnel).

 Doctor warns when the gateway service runs on Bun or a version-managed Node path
 (`nvm`, `fnm`, `volta`, `asdf`, etc.). WhatsApp + Telegram providers require Node,
 and version-manager paths can break after upgrades because the daemon does not
 load your shell init. Doctor offers to migrate to a system Node install when
 available (Homebrew/apt/choco).
