/**
 * @file plugin-bootstrap.js
 * @description Makes AgentHub usable straight from a Claude Code plugin install.
 * Runs from the plugin's `SessionStart` hook and must NEVER block a session:
 * the foreground pass only checks a fast path, then hands the real work to a
 * detached worker copy of itself.
 *
 * The worker installs runtime dependencies, removes hook entries left behind by
 * an older `npm run install-hooks` (they would double-count every event), puts
 * the `agenthub` CLI on PATH, and starts the dashboard server — as a systemd
 * `--user` service when available (see `systemd-service.js`), so it survives
 * reboots without Claude Code being opened first; otherwise a detached spawn
 * scoped to this session, same as before.
 *
 * Everything writable lives under `~/.claude/agenthub/runtime/` — NOT in
 * the plugin cache, which Claude Code garbage-collects and replaces wholesale
 * on every plugin update.
