ci: improve GitHub Actions caching strategy

- Replace manual Go caching with actions/setup-go built-in cache
- Switch from actions/cache to Swatinem/rust-cache for Rust dependencies
- Enable cache-bin to preserve installed cargo binaries
- Add --locked flag to cargo install for deterministic builds
- Use shared-key with runner.arch to separate caches for different architectures

These changes resolve cache conflict issues and improve workflow efficiency.
