Function handleDevtoolsRequest

handleDevtoolsRequest(
    req: Request,
    devtools: DevtoolsPort,
    options: DevtoolsRequestOptions,
): Promise<Response>
Unified devtools request handler.

Routes requests to the appropriate handler based on the URL path:
- {basePath}/core/events → event list (GET)
- {basePath}/stream → live event stream (GET)
- {basePath}/clear → clear buffer (POST)
- {basePath} → dashboard UI (GET)
This lets you wire up a single catch-all route instead of three separate ones.
Parameters
- req: Request
  The incoming HTTP request
- devtools: DevtoolsPort
  The DevtoolsPort instance
- options: DevtoolsRequestOptions
  Devtools route options including base path and access policy
Returns Promise<Response>
Response for the matched sub-route
Example
```
// Next.js catch-all route: app/api/devtools/[[...path]]/route.ts
import { createDevtoolsRoute } from "@beignet/devtools";
import { getDevtools } from "@/server";

export const { GET, POST } = createDevtoolsRoute(getDevtools(), {
  basePath: "/api/devtools",
});
```
