feat: 360-degree omni marking option

- omni_mark: full-sphere sweep (linear_sphere_sweep capsule covering max_range
  around the player) replaces the forward-only ping raycast, so enemies behind
  you / off-screen become mark candidates
- omni_mark_ignore_los: optional sub-toggle, skips line-of-sight checks entirely
- prefer nearest unit on score ties (sweep hit order is arbitrary)
- bypass FOV dot gate in is_target_pingable when omni_mark is on
- LOS check budget 10 -> 16 per frame
