Eyes: a stale binary, and faces carried between screens

The user saw characters without eyes again.

The cause was the binary, not the code. ./target/release/rugrats was built at 18:07 on 2026-10-15, before worklog 84's fix (about 21:00). careful.sh sends this session's builds to /mnt/data/claude/targets/rugrats, so ./target was never rebuilt. The current code draws eyes:

• in the hub's start cinematic: Stu, Didi, Tommy, Chuckie, Phil, Lil;
• in play: Tommy, walking toward the camera.

./target/release/rugrats is now rebuilt from HEAD. Both binaries were shot headless and checked.

The faces between screens. The PlayStation has one VRAM. The characters' texture is loaded once, at boot (0x800186d8), and every cinematic writes its mouths and eyes into it (0x80074ec0, 0x80075304). So play and the next cinematic start from the faces the last cinematic left. The port gave each screen its own VRAM, built from the texture's file.

FaceBlocks (media/face.rs) now copies every mouth and eye block from a cinematic's VRAM when it ends (the opening, and every scene). The app puts those blocks into the next cinematic's VRAM and into the game's VRAM, the game's once for each copy taken (Game::face_serial).

Comparing with and without the copy in play: the texture already has Tommy's open eyes, so the picture is the same at frame 8430. The copy matters when a cinematic ends on a blink or an open mouth.
