chore: working-tree state — anaf snapshots, cron state, KB notes, tools

Pre-existing uncommitted changes swept in with the STT work:
anaf-monitor snapshots/versions, cron job + newsletter state, 9 youtube KB
notes, tools/ocr_bon.py, and tools/tts.py.

Note: the tts.py change breaks 2 truncation tests in test_voice_normalize.py
(sanitize word-count) — flagged for a separate follow-up.
