fix: prevent agent selection dialog from auto-closing + landing page tweaks

- Add _agent_waiting_for_input flag to prevent focus-loss auto-cancel
from dismissing the selection dialog while the agent is blocked
waiting for user input (fixes hang in web/browser mode)
- Replace hardcoded "Env: dev / Status: ready" with description blurb
- Add ASCII robot to landing page graphic
