Details
- Triggered by terminal focus/blur events tracked via the presence system

- Summary is added as a system message of subtype
away_summary - Uses cached parameters to avoid expensive re-computation
- Cannot use tools (text-only generation)
Evidence
Away summary generation (search for "The user stepped away and is coming back")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
