UserContext

Maintains a compressed `## Daily Context` block in the owner's USER.md: an evidence-grounded snapshot of mood, location, week theme, and yesterday/today/tomorrow bullets, inferred from whatever signal sources the setup exposes (calendar, session history, email, long-term memory). Use when the daily context block needs refreshing, when its scheduled job has failed, or when the owner asks for a status snapshot. Keywords: daily context, user snapshot, mood inference, USER.md update, personal briefing. NOT for weather, long-term planning, or advice.
