Pull request overview
This PR implements a multi-protocol dependency proxy with malicious package detection capabilities. The proxy acts as a firewall that checks package requests against the OSSF malicious packages database and blocks flagged packages before they can be installed.
Key Changes:
- Added a caching proxy server supporting npm, Go, and OCI/Docker registries with malicious package blocking
- Integrated OSSF malicious-packages database as a git submodule for detecting known malicious packages
- Created comprehensive test suite covering malicious package detection, proxy blocking, and path parsing
