Agent Platform: polish Inference Broker bullet, add Imperator metacoding

Tightened phrasing — single proxy, named aliases, logic layer shapes
and redirects. The four example behaviors kept in a cleaner list form
(rate-limit fallback, size-based routing, format reshaping, content
dispatch). Added the parallel to Context Broker: the Inference Broker
has its own Imperator that metacodes aliases, routes, and transformation
logic.

-        <li><b>Inference Broker</b> — a proxy for every model call in the ecosystem, local and cloud. An <b>alias, routing, and logic layer</b>: a named alias can route directly to a specific model (<code>gpt-5.4</code> → GPT 5.4), or it can run through a configurable logic layer that shapes and redirects the call. Examples: fall back to a secondary model on a rate-limit error; route small calls to local inference and large ones to the cloud; receive a request in OpenAI format and reshape it for an Anthropic endpoint; dispatch code-authoring requests to one model and code-testing requests to another.</li>
+        <li><b>Inference Broker</b> — a single proxy in front of every model call across the ecosystem, local or cloud. Clients invoke a named alias; the alias either points straight at a specific model, or runs through a logic layer that shapes and redirects the call. That logic can fall back to a secondary model on a rate-limit error, send small requests to local inference and large ones to the cloud, reshape an OpenAI-format call for an Anthropic endpoint, or dispatch by content — code authoring to one model, code testing to another. Like the Context Broker, its Imperator can metacode new aliases, routes, and transformation logic.</li>
         <li><b>Conversation Broker</b> — agent-to-agent messaging on an email-style model: addressed communication, threading, participant history, delivery notification, loop protection. Internal, controlled, no SMTP required.</li>
