When listNewMessageIds hits MAX_HISTORY_PAGES the cursor correctly stays frozen, but if pages 1-3 are already deduped the poller re-fetched them forever and never reached page 4+ — silently skipping new mail. Persist history_page_token (migration 32) once a truncated slice is fully worked; the next poll resumes from that nextPageToken with the same cursor. Clear the token on a complete listing or when a batch cap leaves unprocessed ids in the current slice. Co-authored-by: schmug <schmug@users.noreply.github.com>

When
listNewMessageIdshitsMAX_HISTORY_PAGES, the cursor correctly stays frozen. But if pages 1–3 are already deduped, the poller re-fetched them on every tick and never reached page 4+ — silently skipping new mail for busy sidecar mailboxes.Test plan
npm testpasses locally (59 targeted tests: gmail-client, workspace-poll, sidecar-state)Notes for reviewer
Minimal fix scoped to the page-cap continuation path. No changes to cursor-advance semantics for non-truncated listings.
