- Add preservePath field to redirect schemas for prefix-based redirects
- Implement preservePath logic in middleware to append remaining path to target URL
- Add /git redirect to https://github.com/just-be-dev with preservePath enabled
- Enables short GitHub URLs like /git/repo-name to redirect to org repositories
