chore: update repository URL after GitHub rename

GitHub renamed the repo from donglora/protocol to donglora/protocol-rs (the Rust implementation is now distinguished from a forthcoming protocol-py sibling). Update Cargo.toml repository/homepage and README badge / link URLs so the published 1.0.0 crate points at the new location.
