feat(triage): add a per-sweep timestamp to auto mode output

Auto-mode sweeps now end with the date, time, and timezone on their own final line, so an away reader gauges each summary's freshness at a glance without computing it. The stamp prints on every sweep, including a quiet "no changes" one — there the stamp is the proof the loop ran.

Same-day addendum to the work-project auto-mode proposal.

 - The interval loop is the delivery mechanism (CronCreate session-only, or a durable schedule); the mode is the behavior. They compose.
 - "Responses awaiting acknowledgment" tracking needs a small piece of state. In a session it can live in the session-context log; if the engine wants it durable across sessions, a tiny =.ai/triage-unacked.org= (or similar) is the natural home — flagged as a design choice for the rulesets side to decide.

+Add a third end-of-sweep output line: the current date/time/timezone, on its own final line, via =date "+%A %Y-%m-%d %H:%M:%S %Z (%z)"=. Reason: on an away day with frequent unattended sweeps, the per-sweep stamp shows how fresh each summary is at a glance. Sweep output sections become: (a) Deltas, (b) Responses awaiting acknowledgment, (c) the timestamp. Implemented 2026-06-15; the stamp prints on quiet sweeps too, as proof the loop ran.
