  countDiffLines, escapePathPreserveSlashes) from github.go
- Update all callers (db2sdk, exp_chats, gitsync) for new signature
- Add error logging for provider construction failures
- Thread context through provider resolution

#25652 - feat(coderd/externalauth/gitprovider): add GitLab provider

  FetchPullRequestDiff, FetchBranchDiff, ResolveBranchPullRequest
- Handle nested groups, forks, and self-hosted instances
- Rate limit detection on both library and raw HTTP paths
- URL parsing/building with NormalizePullRequestURL support
- Unit tests covering error paths, URL parsing, state mapping
- Document GitLab configuration and known limitations
