Overview

Path B for #35 access-based staleness — sweep-derived rather than per-recall written. Scans activity_events from both stores, projects the most recent recall/context-injection touch per (scope, fact_id), and bulk-updates facts.last_recalled_at across both DBs.

Cross-DB by design: project DBs record activity_events for both project and global facts (a recall fired from a project context that returns global facts is logged in the project DB), so a per-store refresh would silently miss global facts entirely.

Lookback bounds keep the scan O(window), not O(history).
