refactor(ci): Consolidate Rust checks with optimised toolchain setup
Merge rust-checks.yml into prek-checks.yml for a unified workflow that runs formatting and clippy/test checks in parallel jobs. Add reusable composite actions: - setup-rust: Smart Rust toolchain management with caching * Uses cargo-binstall for pre-built binary downloads * Integrates Mozilla sccache-action for compilation caching * Workspace-relative paths for better cache control * GitHub token support for improved rate limits - setup-llvm-with-apt: LLVM installation with native dependencies - detect-runner-os: Consistent OS detection for cache keys Key improvements: - Install prek via cargo-binstall --git (crates.io outdated at v0.0.1) - Download timelord-cli from cargo-quickinstall - Set BINSTALL_MAXIMUM_RESOLUTION_TIMEOUT=10 to avoid rate limit delays - Default Rust version 1.87.0 with override support - Remove redundant sccache stats (handled by Mozilla action) Significantly reduces CI runtime through binary downloads instead of compilation while maintaining all existing quality checks.
