joungmin 673ce08d84 feat: add velocity entry, fast-poll thread, tighten BEAR threshold ...

- Add velocity-based entry signal in strategy.py (VELOCITY_THRESHOLD=0.10,
  VELOCITY_MIN_MOVE=0.5%, VELOCITY_MIN_AGE_M=5)
- Add fast-poll thread in daemon/runner.py (SIGNAL_POLL_INTERVAL=15s)
  for sub-minute velocity event detection
- Add vol_ratio tiered condition and get_active_signals() to strategy.py
- Change BEAR_THRESHOLD -1.0 → -0.5 in market_regime.py to catch
  slow downtrends earlier (weighted 2h score)
- Expand sell_reason VARCHAR2(500) in price_db.py DDL
- Add velocity_backtest.py and sim10m.py for strategy experimentation
- Update STRATEGY.md: correct regime algorithm description (weighted 2h
  score, not BTC 1h ±5%), add fast-poll/velocity sections, add backtest
  section D, add change history table
