CI/CD / build-and-push (push) Successful in 1m51s
feat(observability): fine-grained metrics for summary, trades, and cycle log
api/summary — new fields:
  open_trades_count, closed_trades_count, cash_available (bankroll−deployed),
  legacy_incomplete_count, reentry_guard_blocks_24h
  parallel fetch via asyncio.gather for sub-ms overhead

api/trades?status=open — trade enrichment:
  days_open (float, rounded to 1 decimal)
  signal_components {fg, mom, news, mfld} parsed from reasoning via regex
  Old trades without feat_str in reasoning return signal_components: null

bayesian.py — reasoning now embeds feat_str:
  "fg=+0.0600 mom=+0.0000 news=+0.0000 mfld=-0.7483 |"
  Manifold counters: _manifold_fetched / _manifold_on_trade per cycle
  get_cycle_stats() exposes manifold_matches_accepted / manifold_matches_rejected

bot/main.py — CYCLE SUMMARY 4 new fields:
  reentry_guard_blocked, legacy_incomplete_seen,
  family_conflicts_prevented, manifold_matches_accepted/rejected
  legacy_incomplete_count queried from DB once per cycle

db.py — get_legacy_incomplete_count(): open trades with NULL edge_net
