// POST /api/config/refresh — wraps `refreshScheduledSkills()` +
// `refreshUserTasks()` into one endpoint so the config-refresh
// PostToolUse hook (#1283) can fire-and-forget after Write/Edit of
// the relevant config files without knowing which refreshers exist.
// Serves the `mc-manage-skills` + `mc-manage-automations` preset
// skills (split out from the original `mc-settings` in #1295).
//
// Best-effort by design: failures from one refresher don't block the
// other; the response is always 200 with a per-refresher status so the
// caller (the hook) can log on errors but never has to abort.
