refactor(ci): remove redundant version checks in vorpal.yaml

Removed unnecessary version checks for cargo, rustc, nickel, and protoc in the GitHub Actions workflow file to streamline the CI process.

feat(worker): add async signature decoding

Introduced an async function `decode_signature` to handle the decoding of source data signatures in a non-blocking manner. Updated the `run` function to utilize this new async decoding method, improving error handling and code readability.
