RAG-grounded code generation — retrieves attune context and emits answers with source citations

Notes & tips

• Depend on the documented public surface. The supported API is RagCodeGenWorkflow and its async execute, and the WorkflowResult it returns. Names with a leading underscore — _get_pipeline, _run_agent_generate, _record_feedback — are internal.
• Prefer path over cwd. cwd is a deprecated alias kept for back-compat; pass path= to scope the agent's file tools.
• Use k and depth to tune cost. Fewer passages and a shallower depth make a cheaper, faster run.
• Read the citations. The ## Sources block and metadata["citation"] let you verify each claim against the real attune-help template.
