v2.8.3 — Digest cache: skip Gemini on same-day re-runs

Digest cache (GitHub Actions cache)

Publisher (04.1.agentic_v2_publish.yml) and weekly cron (09.weekly_digest.yml) now cache data/news_digest.json with key news-digest-YYYY-MM-DD.

Behavior:

• First run of the day → generates digest with Gemini, saves to cache
• Re-run same day (e.g. after publisher crash) → restores from cache, skips Gemini entirely
• Next day → cache miss, fresh digest generated

Savings per skipped Gemini run: ~20 minutes CI time + 66 API calls

Cache expires automatically after 7 days per GitHub Actions policy.
