unregister
Remove an agent from the server. The next getApp() builds the app without the
agent’s routes, and a server started with run() serves each request from the current
app, so the routes stop being served. The agent no longer appears in getAgents() or
the root listing endpoint.
Parameters
route
The route of the agent to remove (e.g., "/sales").
Returns
boolean — true if an agent was registered at that route and was removed,
false if no agent was found at the route.
