engine(macos-arm64): publish 51ed21d5 — shadow pass diet (static tile budget, live caster screen-size cull, inverted static contract switch) + GPU device-lost diagnostics, on top of 4.7.2 + static shadow cache + get_video_adapter_memory; GodotSharp regenerated; smoke on Kraken: 0 wrapper errors, inverted contract 1379 → 956 draws on the staged village; windows-x64 untouched (still b1bc0aef)

-Mac is engine `2caca361` as of 2026-10-05 (`--version` prints `4.7.2.stable.mono.custom_build.2caca3619`): 4.7.2 + static shadow cache + the video adapter memory query. Windows is `b1bc0aef` (2026-09-28, 4.7.2 + static shadow cache) and gets the memory query when Forge rebuilds from main. The engine source repo stays private. Check `manifest.json` for sha256.
