[BUG] Claude Code on the Web: Git LFS not supported — proxy rejects LFS batch API with "invalid git path"

What's Wrong?

Repositories that use Git LFS cannot pull LFS-tracked files
in Claude Code web sessions. The local GitHub proxy
(127.0.0.1) actively rejects the LFS batch API endpoint,
so all LFS-tracked files remain as pointer stubs throughout
the session.

The proxy seems to have a path validation check that
only allows standard git smart HTTP protocol paths. It
rejects the /info/lfs/objects/batch URL pattern with the
error Proxy error: invalid git path.

What Should Happen?

The GitHub proxy should pass through Git LFS batch API
requests (/info/lfs/objects/batch) to GitHub, allowing
git lfs pull to download LFS objects. Repositories using
Git LFS should be fully functional in web sessions.

Steps to Reproduce

$ curl -s -o /dev/null -w "%{http_code}" -X POST \
http://127.0.0.1:<proxy-port>/<org>/<repo>.git/info/lfs/objects/batch
502

Response body: Proxy error: invalid git path

1. Create a repository that uses Git LFS (e.g. tracking

*.pdf or *.pkl files via .gitattributes)

1. Start a Claude Code web session on that repository
2. Run git lfs install && git lfs pull
3. Observe: 502 error with "invalid git path"
4. The LFS-tracked files remain as ~130-byte text pointer

stubs instead of actual binary content
