Attempt to fix CI (#162)

* Temporarily remove Swift 6.1 from the CI matrix.

mlx-swift-lm 3.x upgraded Swift version, which fails to compile with
strict concurrency for SDKs earlier than 26.

An alternative would be to test the "MLX" trait separately on just Xcode
26, and keep the full matrix for the rest of traits.

* Use NIOCore to restore Linux compatibility.

Graph resolution changed after the bump to mlx-swift-lm 3 and
it looks like NIOFoundationCompat is no longer there.
