ci: Update prefligit to prek

The prefligit project has been renamed to prek due to typosquatting
concerns. This updates our CI to use the new name and recommended
installation method via uv, which significantly reduces setup time
compared to cargo install and includes automatic caching.

- Replace outdated static prefligit action with direct prek invocation
- Use uv as recommended by upstream: https://github.com/j178/prek
- Update check-byte-order-marker to fix-byte-order-marker (deprecated)
- Simplify workflow by removing unused ref calculations

The same .pre-commit-config.yaml works unchanged. Developers can
install locally with 'uvx prek install' or other methods from the repo.
