Two changes that together cut OpenRouter spend ~50% and give the daily
log temporal awareness.
1. CadencePolicy (app/services/cadence.py): expensive AI jobs only
fire hourly during the EU/US active window (Mon-Fri 07-21 UTC).
Off-hours weekdays throttle to every 4h; weekends to every 12h.
ai_log_job and indicator_summary_job both consult the policy before
doing real work; market/news/portfolio ingest jobs stay hourly
(cheap, no API cost). Skipped runs land in job_runs with status
'skipped' and the throttle reason in error.
2. Update mode for ai_log_job: when an earlier log exists for the
current UTC day, it's passed to the model as 'Earlier log from
today (generated HH:MM UTC)'. The system prompt grows an Update
mode section instructing the model to revise — not restart — and
anchor on what has CHANGED since the earlier draft. The TL;DR
leads with intra-day change when meaningful, the watch list evolves
rather than restarts. PROMPT_VERSION bumped to 5.
