* docs(extensibility): reorganize extensibility and middleware guides
Add an extensibility overview that introduces the extension protocol and
links every extension point, and move extension caller authentication to
a shared page used by middleware and gateway interceptors.
Split the supervisor middleware guide into an overview, a Configure and
Operate guide, and a Middleware Operations reference for service authors.
The overview explains when to use middleware, shows where it runs, lists
current limitations, and defines the service contract. Configure and
Operate covers policy attachment, service registration, failure behavior,
and observability. Middleware Operations describes HTTP request, HTTP
response, and WebSocket message operations with shared inputs and results,
per-operation diagrams, and detail accordions.
Pin page slugs so links resolve, redirect the replaced dev middleware
URL, and update reference and architecture links.
