- Raiders now roll an attack comm on-screen (50%) or on rolling-wave arrival (20%), and a defeat comm on kill (20%), driven by per-type config in combat.json
- New bounty-attack comm fires when the wanted leader's fight stands up in GameScene._fireBountyEngagements
- Ship 12 pirate speech clips, 3 enemy video clips, and register three new senders (pirate, pirate_defeat, pirate_bounty) in comms.json
- Wire onComm seam through CombatSystem so the scene can arm CommsHub triggers; rolls are no-ops when the seam is absent
- Add combat, bounty-hunt, and comms test coverage for the new roll logic, trigger arming, asset presence, and roster count
