Two-phase monitor, integer shares, and daily log

- Monitor now runs morning (9:45 → signals) and evening (4:35 → execute)
  instead of single daily run; falls back to auto if morning missed
- Add --integer-shares flag for whole-share-only trading (no fractional)
- Add daily_log to state: each day records holdings, cash, and operations
- Add 'log' subcommand to view daily snapshots with date range filter
- record_daily_snapshot() called from both simulate and auto commands

+### Option 1: tmux monitor (recommended)
+
+Two-phase daily schedule — morning (open prices → generate signals) and evening (close prices → execute trades):
+
+```bash
+tmux new -s quant
+uv run python trader.py monitor --market us --strategy recovery_mom_top10
+# Ctrl-B D to detach; tmux attach -t quant to reconnect
+```
+
+If monitor starts mid-day (after open, before close), it automatically falls back to `auto` mode for the evening phase.
+
+### Option 2: Cron
 
 Run daily after market close. The `auto` command is idempotent — safe to re-run:
