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

Side B fixes real bugs (hardcoded hostnames breaking OAuth redirects on custom hosts/staging, wrong deploy branch triggers) by centralizing base-URL logic and using runtime env/window.location, delivering an actual correctness improvement across multiple integrations. Side A adds a substantial new dev-only tool, which is useful but purely additive tooling with no bug fix, and its value is more speculative/internal compared to B's concrete production-affecting fix.
