This pull request introduces a new utility for cloning remote Git repositories to deploy functions, along with a helper for secure path resolution. The implementation is robust, with good error handling, retry logic for network operations, and comprehensive tests. I've provided a couple of suggestions to refactor parts of the remoteSource.ts file to improve code clarity and maintainability.

Code Review

This pull request introduces a utility to clone remote Git repositories for deploying functions, along with a path resolution helper. The implementation is well-structured, using a GitClient interface for testability and providing helpful error messages for common failures. My review identified two high-severity issues: a potential bug in error handling where the original error object could be lost, making debugging difficult, and a lack of test coverage for the success paths of the main cloneRemoteSource function. Addressing these points will improve the robustness and reliability of this new feature.

Code Review

This pull request introduces new utility functions for handling remote Git sources for function deployments. It adds cloneRemoteSource to clone a repository, along with a GitClient interface and a default implementation using spawnSync. It also includes a path helper resolveWithin to securely resolve subdirectories within a repository, preventing path traversal vulnerabilities. The changes are well-tested with new spec files for both remoteSource and pathUtils.

My review includes a couple of suggestions to improve code style and reduce duplication in the new remoteSource.ts file. Overall, the implementation is solid and the error handling is comprehensive.
