fix(triage-intake): guard personal-gmail sweeps against the Gmail 100-cap

The google-docs MCP listMessages tool caps at maxResults=100 and exposes no pageToken, so an unread pile over 100 truncates silently and every later anchored sweep skips the tail below the cap. That's how a 300+ backlog built up unseen by 2026-07-08. Two Scan-section rules close it: when a scan returns exactly 100, walk the tail in date slices and dedupe by id, and never report resultSizeEstimate as a count. A cheap backlog-residue probe each sweep (before:<anchor>, maxResults=5) surfaces pre-anchor unread loudly, so an anchored "no changes" can't mask a window the scan never saw.

personal-gmail is the only gmail-family plugin here, so it's the only file that changed.
