~anthropic/claude-sonnet-latest → B (6:4)

B is a small, targeted bugfix that defines the missing GITHUB_API_BASE_URL to prevent a NameError in the OAuth callback, a real correctness fix. A is a large refactor replacing a working rule-based URL engine with a new graph/DFA architecture but deletes all existing tests without adding new coverage in the diff, making its correctness and lasting value harder to verify despite its scope.
