stable Plugin backend Show on the zone map

Connects the plugin's own UI, its server code, and outside services. With this, a plugin can:

Typed RPC, HTTP & WebSocket routes, realtime push

What it gives you

• Call its server from its UI over RPC, with arguments and results checked against a schema
• Publish RPC methods with experimental_discoverable and registration/method experimental_description; other plugins discover implementations and copy their published JSON Schemas using bb plugin rpc inspect
• Serve exact-path HTTP and WebSocket routes other systems can call, webhooks included
• Push messages to every open bb window, so the UI does not have to poll

Brief for agent…as a bb mentionAdd to set

The brief is Markdown, written for a coding agent: what the capability is, where it registers, every SDK symbol with a pinned permalink, the rules that bite, and what done means.
