fix(filter): deprioritize recent movers instead of dropping, exempt mean_reversion pipeline

- Change recent_mover_action default from "filter" to "deprioritize" so candidates
  that moved >10% in the past 7 days reach the ranker (with lowered priority + context
  annotation) rather than being silently dropped
- Exempt mean_reversion pipeline candidates (rsi_oversold) from the recent-mover action
  entirely — stocks that pulled back hard are the signal, not a disqualifier
