Submit Feed Input Stream

Stream agent processing of feed input via Wire Protocol.

This is the agent-first approach: the agent classifies input, searches the knowledge base, and provides streaming responses.

Returns Server-Sent Events (SSE) with Wire Protocol messages:

• turn_begin: Agent turn started
• step_begin: New processing step
• text: Text content from agent
• thinking: Agent's reasoning (if enabled)
• tool_call: Agent called a tool
• tool_result: Tool returned a result
• turn_end: Agent turn completed
