/**
 * Update Service — in-place update from GitHub + Fly restart.
 *
 * Flow:
 *   1. Clone latest code from GitHub (shallow, depth 1)
 *   2. Install deps + build + pack tarball
 *   3. Extract tarball over the installed extension
 *   4. Restart the Fly machine via Machines API
 *
 * All steps report progress via a callback so the user sees
 * live updates in Telegram.
 *
 * Prerequisites:
 *   - FLY_API_TOKEN (for restart) — already required for /flykeys etc.
 *   - git, npm, node in the container — present in Dockerfile layer 1
