I Luk Kim 867d70afae fix: correct simulation loop and equity curve calculation after real-data testing
- BacktestRunner.run() now iterates all NYSE trading days (not just candidate
  days) via SnapshotStore.all_trading_days() so stop/target/time exits are
  checked every day, not only on days with new candidates
- Record initial DailyPortfolioState before simulation loop starts so
  total_return_pct is computed relative to the true initial equity (100k),
  not the first post-entry equity snapshot
- SnapshotStore._fetch_event_metadata() now synthesises event_timestamp from
  event_date + 21:00 UTC when filed_at_utc is NULL (transparent enrichment at
  loader boundary, not silent substitution in selector)
- SnapshotStore._async_load() maps event_close → entry_price_est when the
  column is absent, and derives score from abs(reaction_day_return) when the
  Parquet snapshot has no score column
- Add --snapshot-dir CLI flag to BacktestRunner to override the default
  parquet_dir base path (needed for non-standard snapshot locations)
- Fix integration test assertion: total_trading_days >= 2 (was == 2)
- Add configs/experiments/realdata_test_v1.json for real Phase 3 snapshot runs
