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

A is a small, clearly-explained config fix that removes real maintenance friction (new test files no longer need manual registration) and is low-risk and self-contained. B is a large refactor with a vague message ('url stuff'), deletes the old engine and its inline tests but the patch shown never introduces the new graph.rs/parse.rs modules it depends on, leaving the actual replacement logic unverifiable and the commit's completeness in doubt.
