Concrete adapter classes (AnthropicAdapter, GitHubAdapter, etc.) are no
longer imported at the top of team_runner.py. Instead, each registry maps
short names to 'module.path:ClassName' strings resolved lazily via
importlib.import_module at instantiation time.
This means:
- Adding a new adapter requires only an entry in the registry string dict
(or a full dotted path directly in team.yaml) — no changes to TeamRunner.
- Third-party / custom adapters work out of the box: set e.g.
adapters.llm: mypackage.llm.openai:OpenAIAdapter in team.yaml.
- The runner no longer hard-wires knowledge of which concrete classes exist.
