v1.2.0 — daily news digests
Switch AI news from weekly to daily digests: one entry for a normal day of work, up to newsMaxPerDay (2) when the day has clearly distinct features, 0 for trivial days. Livelier, "build in public" cadence while staying adaptive, idempotent (past days frozen, current day refreshed), and rate-limit-safe (steady state ~2 model calls per sync; backfill capped per run).
Config: newsWeeks / newsMaxPerWeek → newsDays / newsMaxPerDay.
Verified end-to-end against Supabase: distinct per-day digests (1-2/day), convergence to current-day only on re-syncs. typecheck / lint / build green.
