M1: rörelse, kollision, kamera, scener, tileset, skärmdumpar, CI

- internal/sim: rutbaserad Mover (4 riktningar, riktningsbyte vid rutgräns,
  bildrute-exakt ankomst) och Camera (följer, klampar, centrerar små kartor),
  med tester
- internal/game: scener meny -> bana -> resultat, tangentbord + gamepad,
  tileset och spelaranimation, HUD, skriptläge (-script) för deterministiska
  skärmdumpar och tester
- tools/genart genererar placeholder-grafik (tiles.png, player.png);
  tools/shots tar doc/img/*.png som README och wiki visar
- bana 002-shinjuku (33x21) för kamerascroll; level.List/LoadFile/TrainAt
- .gitea/workflows/release.yaml: vet + test + linux/windows-zippar till
  rullande latest på brasse-linux01-runnern (linux-amd64)
- docs: roadmap M1 klar, tester, plan, README med bilder och styrning
