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

Side A fixes a real bug (empty external garden index due to bogus parent), cleanly restructures the GitHub resolver into a resolvers/ module with a proper card schema/renderer, and adds targeted unit/integration tests validating the new behavior. Side B is largely infra/deploy plumbing (Dockerfile, fly.toml, CI) plus a sizable dashboard/SSE feature for a separate constitution.py service, which is useful operationally but is less about core product correctness and mixes config, UI, and scattered test tweaks.
