~anthropic/claude-sonnet-latest → A (3:2)

Side A is a minimal, precise fix that defines the missing GITHUB_API_BASE_URL to resolve an actual runtime NameError crash in OAuth callback, delivering clear correctness value. Side B is a larger UI refactor (grouped CLI panel with hover-to-copy) that is reasonable but purely cosmetic/feature polish with more surface area for regressions and no critical bug being fixed.
