Add crane (github:ipetkov/crane) for building and testing the Rust workspace. Crane provides incremental builds by caching dependencies separately from source changes. Key changes: - Add `nix/crane.nix` module with craneLib setup using fenix toolchain - `cargoArtifacts` via `buildDepsOnly` enables dependency caching - Expose crane checks: `cargo-fmt`, `cargo-clippy`, `cargo-nextest` - Export `packages.default` as the crane-built crate - Use `craneLib.devShell` with `inputsFrom` for inherited build inputs - Include musl target configuration on Linux for static linking Benefits: - Faster CI via cached dependency artifacts - `nix flake check` runs fmt, clippy, nextest, and build - Shared artifacts between clippy, nextest, and coverage derivations Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
