Enhances Rust CI workflow efficiency and features

Adds concurrency controls to cancel redundant runs and disable fail-fast for comprehensive matrix testing. Switches to cargo-nextest for faster test execution and adds documentation tests. Updates minimum supported Rust version and simplifies MSRV checks. Improves code coverage setup with LLVM tools and removes unused benchmark job.
