feat(triage): deltas-only sweep summaries and silent telegram dev groups

A sweep now reports only what changed: a new invite, a moved or cancelled event, a message needing attention. Unchanged sources get no block. An all-quiet sweep renders as one line. Scan failures keep their loud banner and the suggested-actions line stays when actions are queued.

Telegram dev-community group traffic (zed, GNU Emacs, Kitty) is dropped from sweep reports entirely unless Craig asks. Real DMs from known contacts still surface as Action.
