- Change gitprovider.New to return (Provider, error)
- Extract shared helpers (parseRetryAfter, checkRateLimitError,
  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
- Implement full Provider interface: FetchPullRequestStatus,
  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

#25653 - test(coderd/externalauth/gitprovider): add GitLab VCR integration tests
- FetchPullRequestStatus: 4 fixtures (open, conflicts, merged, closed)
- FetchPullRequestDiff: 4 fixtures
- FetchBranchDiff: 3 fixtures (open, deleted, fork)
- ResolveBranchPullRequest: 3 fixtures
- go-vcr cassettes with sanitized GitLab API responses
