**Fixes new debugger launch flow on Android:**
D49158227 aimed to improve proxy-safe behaviour for remote dev servers by auto-detecting the appropriate server URL for clients using the `Host` header (etc) from the HTTP request. However, this approach broke the local case for Android emulators and externally connected devices since they would originate from a device-relative server hostname — e.g. `10.0.2.2` for the stock Android emulator.

This commit reverts to an explicit approach where callers specify the base URL to the dev server that should be addressible from the development machine — now as a single `serverBaseUrl` option.
**Changes**
- Adds new `serverBaseUrl` option to `createDevMiddleware`, designed to be the base URL value for constructing dev server URLs returned in endpoints such as `/json/list`.
- This changes little for the `localhost` case (now enabling `https://` URLs), but enables remote dev server setups to specify this cleanly.
- Updates call site in `community-cli-plugin`.

Pull Request resolved: https://github.com/facebook/react-native/pull/39423
D49158227 made the CDP WebSocket URLs returned from `/json` proxy-safe by using the Host header (etc) from the HTTP request. This did *not* fully fix the related `/open-debugger` endpoint, because the original headers were being lost in the internal `fetch('/json')` call.
Here, we eliminate that `fetch` call, and instead give the `/open-debugger` handler direct access to the method on `InspectorProxy` that backs the `/json` endpoint. This allows us to pass in an appropriate base URL derived from the headers seen by `/open-debugger`.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/39394
* Constructs DevTools frontend WebSocket URLs with a client-accessible host, port and scheme derived from the initiating HTTP request (`/json` or `/open-debugger`), instead of from the static `host` and `port` parameters provided to `createDevMiddleware`. This results in more proxy-safe behaviour.
* Removes the now-unused `host` and `port` parameters from `createDevMiddleware`.

Changelog: [Internal]
1. Adds an `unstable_experiments` option to `createDevMiddleware` in `react-native/dev-middleware`.
2. Adds `enableCustomDebuggerFrontend` (default `false` for now) as an experiment flag controlling whether the new debugger frontend (D48680624, D48682302) is in use. We plan to enable this by default in RN 0.73 after additional testing.
If enabled, the new debugger frontend will only be used for the `/open-debugger` flow

Pull Request resolved: https://github.com/facebook/react-native/pull/39242
Reverts external behaviour of https://github.com/facebook/react-native/pull/39122.
- `/json/list` once again returns the built-in `devtools://devtools/bundled/js_app.html` URL — effectively freezing the current experience in Flipper.
- `/open-debugger` continues to use the *new* frontend via `getDevToolsFrontendUrl`.
- *Eventually*, we'll want to align this as the returned `devtoolsFrontendUrl` value once Flipper is out of the picture.

Updates the `devtoolsFrontendUrl` value returned in the `/json/list` endpoint, to match the fixed DevTools frontend revision we set for `/open-debugger` — which now uses this as the source of truth.

Pull Request resolved: https://github.com/facebook/react-native/pull/39107
Augments D48466760 to report debugger commands (request/response pairs) through `EventReporter`. With the appropriate backend integration, this can help validate the correctness/completeness of the CDP implementation (in the client, proxy and server) and measure the latency of debugger commands - more accurately, the time between the proxy receiving a command from the client and receiving the corresponding response from the server.
Most of the new logic here is in the `DeviceEventReporter` class, which is responsible for associating responses with requests. Requests are kept in a buffer with a 10s TTL which serves as a timeout in case of an unresponsive server.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/39091
Changelog: [Internal]
Adds a simple typed logging hook to `react-native/dev-middleware`. This is intended to allow integrators to receive events from the dev server, apply any relevant sampling/processing, and log them to a backend. (To be clear, the open source version of React Native does not and will not collect any data.)
WARNING: The API will evolve over the coming weeks/months and is *not guaranteed to be stable* - it might even break between patch releases.

- Documents migrated endpoints + usage of `createDevMiddleware()` in README.
Changelog: [Internal]
Metro changelog: None (`metro-inspector-proxy` is now an internal component of `react-native`, covered in the [release notes for 0.78.1](https://github.com/facebook/metro/releases/tag/v0.78.1))
