Verified all prompt-injection framework models against the real Python
SDK sources:
- OpenRouter: the official openrouter SDK uses client.chat.send(messages=)
(not chat.completions.create), client.embeddings.generate(input=) (not
embeddings.create), and client.responses.send(input=, instructions=).
Corrected the framework qll and model, and fixed the test files that
used the wrong API.
- Anthropic: added the managed-agents system prompt sink
(beta.agents.create/update Argument[system:]).
- Google GenAI: added models.edit_image Argument[prompt:] as user content.
OpenAI, agents and LangChain models were confirmed correct against their
SDK sources.
