lc0 0.1.0

Lc0 Flutter no GPU

0.1.0

Initial release.

• Embeds Lc0 v0.32.1 (CPU-only, BLAS/Eigen backend) for iOS and Android, driven over UCI through Dart FFI.
• An engine is a handle: Lc0.create() starts one and completes once it has answered uciok, dispose() releases it, and the handle is single-use. Only one engine may be live at a time -- lc0 keeps its state in process globals -- which create() enforces by throwing a StateError.
• The engine reads and writes its own private streams instead of the process's stdin and stdout, so the host app keeps its output and another engine can be resident alongside lc0.
• state and diagnostics report where a start got to (Lc0Phase, the step within it, how long it has been there and the last native error), which is the only way to see a wedged engine from Dart.
• Ships as a Swift package and a podspec on iOS, so it builds whether or not the host app has Swift Package Manager enabled; the engine's sources are vendored rather than fetched at build time, and lc0.patch is the diff from a pristine v0.32.1.
