AgentHub/scripts/cc-update-all-helper.js

#!/usr/bin/env node
/**
 * @file Detached worker for the dashboard's "Update all" button. Runs the whole
 * batch and writes each step's outcome to `cc-update-all.json` in the runtime
 * directory as it goes, so the UI can follow along by polling.
 *
 * Order, and why:
 *   1. `claude plugin marketplace update` (no name = every marketplace) — a
 *      plugin update can only see a version its marketplace already knows about.
 *   2. `claude plugin update <id> -y` for every installed plugin EXCEPT the one
 *      the dashboard itself runs from.
 *   3. That one last, followed by `plugin-bootstrap.js --force` from the NEW
 *      cache directory — this stops the dashboard server and starts the
 *      replacement. Anything ordered after it would run while the server is
 *      down, which is exactly why it is last.
 *   4. `/reload-plugins` + `/reload-skills` typed into the live lane panes.
 *      Deliberately after everything: one reload picks up every pending change.
 *
 * Spawned detached precisely because step 3 kills its parent. It must never
 * throw its way out without a terminal journal entry — a silent death would
 * leave the UI polling a batch that says "running" forever.
