Start with the reported `yt build` and `yt ls` output, focusing on the `minar` → `minar-platform` → `minar-platform-posix` dependency chain. Check whether `minar-platform-posix` is available in the public module registry and confirm that the dependency can be resolved so the BLE_GAPButton build completes.
