feat(insights): Telegram alerts + daily brief push notifications
apps/worker/src/lib/telegram.ts:
- sendTelegram() with Redis-backed dedupe (NX SETEX, 1h TTL)
- Helpers: alertP0Insight, alertRegression, alertSanitizationAnomaly, alertBudgetCap
Wired into:
- analyze.ts: P0/P1 insight creation → instant alert (dedupe per insight_id);
budget guard halt → daily cap alert (dedupe per state per day)
- validation.ts: regression detected (≥3 sessions w/ same fingerprint after shippedAt)
→ alert (dedupe per insight_id)
- compress-sessions.ts: sanitization anomaly (>500 tokens, 0 PII matches)
→ alert (dedupe per session_id) — possible PII leak warning
Daily Brief (jobs/daily-brief.ts):
- Cron @05:00 UTC (= 08:00 Europe/Istanbul)
- 24h: sessions/insights/cost/cache-hit + 3 top priorities + 7d shipped/validated/regressed
- POST /api/insights/brief/send for manual trigger / smoke test
Env: TELEGRAM_BOT_TOKEN, TELEGRAM_CHAT_ID, PANEL_PUBLIC_URL (Coolify both apps).
