fix(qw1): bus event lea:monitor_routed + cablage offset côté executor Agent V1

Cleanup post-review QW1 :
- Émission bus lea:monitor_routed dans /replay/next (idx, source, replay_id, action_id, offset, wh)
  via logger.info "[BUS] lea:monitor_routed ..." (le serveur streaming n'a pas
  de SocketIO local, agent_chat émet déjà lea:* sur 5004 ; ici on logge en INFO
  bien lisible, prêt pour un parser/pont futur)
- Executor Agent V1 (deploy/windows_client) lit action.monitor_resolution.{offset_x, offset_y, idx}
  et applique l'offset aux coords absolues du clic/type/scroll/popup quand idx >= 0
- composite_fallback (idx=-1) : pas d'offset appliqué (backward compat mono-écran)
- Log INFO "QW1 monitor cible idx=N source=X offset=(dx,dy) — appliqué aux coords"
  émis une fois par action quand un offset non nul s'applique

Tests : baseline 95 passed (e2e + phase0_integration + stream_processor + monitor_router + grounding_offset)
