Remove dev shell and document why tests cannot run in nix build

Remove the devShells.default — nix fmt already provides swift-format
via treefmt, and nix build handles production builds. The dev shell
added no value beyond what these commands already provide.

Document doCheck = false: SwiftPM's swift-test requires
`xcrun --find xctest` which needs Xcode, and corelibs-xctest in nix
only provides the library, not the runner. No Swift package in nixpkgs
has solved this — tests require Xcode: swift test
