Replace local detect-runner-os action with external detect-versions@v1 to
reduce custom action maintenance. Add architecture detection for future
cross-platform support and namespace all cache keys with "continuwuity-"
prefix to prevent collisions with other projects on shared runners.
Updates cache mount IDs in Dockerfiles to match the new namespacing
convention, ensuring consistent cache isolation across CI and Docker builds.
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- Install prek via cargo-binstall --git (crates.io outdated at v0.0.1)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.
