Git Recon: rewatch the in-level set pieces (insertion, jump, extraction...) once seen #4097

Follow-up to #4096 (memories: rewatch a cutscene once you've seen it).

Git Recon's film (the newsreel, the credits) can now be watched again from the menu. Its in-level set pieces can't yet, and they're the most meme-able parts: the helicopter insertion and slow-motion drop, the strike that knocks your gun away (incoming), the roadster jump and dive-roll bail-out, the hovercraft that deflates, the landing craft, the barrage, the extraction up the rope ladder.

Why they weren't in the first cut: apps/git-recon/src/sim/director.ts runs them as live gameplay beats driven by the game state (your input, the squad, the vehicle you're in). They aren't standalone scenes in a SceneTable, so playNamed can't replay them.

Possible approaches, owner to pick:

• Record the beat's camera, stage and the soldiers' positions while it plays, then replay that recording on the level's world (like the newsreel's footage).
• Or restage each beat on a fresh copy of the level, with scripted input (like stageClip in src/sim/credits.ts), and mark it as a memory when the live beat first finishes.

Either way: mark with memories.mark from @rustybuns/util/memories once the beat has been seen to its end, and list it in the menu's "Watch again" row.
