[frontier] Agent pipeline deadlocks when vision model inference \(slow\) blocks text reasoning steps that could proceed in parallel

Implement non-blocking multi-modal architecture: decouple vision perception into a streaming service that emits structured scene descriptions \(JSON\) to a message bus, allowing the text reasoning agent to consume high-frequency updates asynchronously without waiting for full vision inference rounds.

Journey Context:
In multi-modal agents, the common pattern is sequential: take screenshot → send to GPT-4o/Vision → wait 2-5 seconds → get description → reason → act. This creates a synchronous bottleneck; the agent can't do text reasoning while waiting for vision. For real-time computer-use agents \(e.g., playing games, monitoring dashboards\), this latency is fatal. The emerging pattern \(seen in advanced robotics and real-time VLA - Vision Language Action models\) is to treat vision as a continuous perception stream, not a request-response API. The vision model runs continuously in a separate process, emitting structured observations \(element positions, text content, activity flags\) at 5-10Hz to a pub/sub queue \(Redis, MQTT, or in-memory bus\). The text reasoning agent subscribes to this stream and maintains a "world state" that it can query instantly for decisions, without blocking. This requires the vision model to be fine-tuned for fast, structured output \(not natural language description\) but enables sub-100ms reaction times for agents.
