Per-user opt-in to full-history (deep) backfill so a new user's unique channels no longer trigger a big shared-quota burst. - migration 0007: Subscription.deep_requested (default false); seed admins' existing subscriptions to preserve today's global-backfill behaviour - run_deep_backfill is now demand-driven: only channels at least one user has requested are deep-backfilled; recent backfill stays unconditional (cheap) - estimate_deep_backfill ETA helper (quota-bound) surfaced in /api/sync/my-status - POST /api/sync/deep-all to opt all my channels in; PATCH channels accepts deep_requested - UI: per-channel Full history toggle, Backfill everything action, deep progress + ETA in Channels header and Settings - Sync
