feat(apps): post-install prompt to enable bundled agents

Bundled agents install disabled (§8.3), but nothing told the installer
they exist — the app opened empty with the refresher buried in
bg-tasks. After an install that materialized agents, offer to turn
them on: 'Turn on & run now' activates each task and fires a first run
so the app opens with data; 'Not now' keeps them off.
