Daily 09:00 CT browser-session audit. Probes 3 default targets (linkedin,
linkedin, reddit) via Chrome CDP at 9223. URL-redirect detection (more
robust than DOM selectors). Writes ~/.openclaw/state/session-keeper/
<date>.json. Opens approval gates for expired sessions with the exact
CDP-spawn command Cooper taps. Telegram-summary only when something
expired or unknown — silence on all-live is valid.
