Lightweight 404 logging

I’m using atec 404 Tracker to quickly see which 404s hit my site—broken links, common typos, and bot scans. It’s clean and fast: no custom tables; data lives in a single option with automatic cleanup, so there’s no DB bloat. For me it’s perfect for diagnostics and redirect planning. It’s intentionally short-term (not a full analytics tool), and heavy bot noise may need filtering elsewhere—but for a lightweight 404 snapshot, it does exactly what I want.
