d640853f9d ci(docs): Optimise build performance with caching and conditional Node.js
Skip installing Node.js entirely if v20+ is already available, otherwise
install v22. Add npm dependency caching with OS-specific cache keys using
the custom detect-runner-os action for proper cache isolation between
runners. Dependencies normally take just under 10s, so this should more
than halve the doc build time to free up runner slots.

dd22325ea2 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- Install prek via cargo-binstall --git (crates.io outdated at v0.0.1)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.
