- Add lib/zim_monitor.py: polls kiwix-serve OPDS v2 catalog, detects
new ZIMs, reads accurate article count from python-libzim Counter
metadata (not inflated OPDS count), inserts into zim_sources table.
Idempotent on re-run, marks removed ZIMs.
- DB schema: zim_sources, zim_samples, zim_articles tables (created
via sqlite3, not in migrations — matches existing RECON pattern)
- kiwix-tools 3.7.0 installed from binary tarball at /opt/recon/bin/
(Ubuntu 24.04 apt ships 3.5.0 which lacks OPDS v2)
- kiwix.service systemd unit on port 8430
- python-libzim 3.9.0 installed
- Test ZIM: Appropedia EN maxi (496 MB, 19,445 articles)
- Add bin/ to .gitignore (binary tarball, not source)
