Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/40766
This changeset allows users to opt into the new debugger frontend experience by passing `--experimental-debugger` to `react-native start`. **We are defaulting this option to `true`** for now, but will continue to evaluate this feature before 0.73 ships. It restores Flipper (via `flipper://`) as the default handling for `/open-debugger` (matching 0.72 behaviour) when this flag is not enabled.
Detailed changes:
- Replaces `enableCustomDebuggerFrontend` experiment in `dev-middleware` with `enableNewDebugger`. The latter now hard-swaps between the Flipper and new launch flows.
- Removes now-unused switching of `devtoolsFrontendUrl`.
- Implements `deprecated_openFlipperMiddleware` (matching previous RN CLI implementation).
- Disables "`j` to debug" key handler by default.
- Marks "`j` to debug" and `/open-debugger` console logs as experimental.

Hotfix for exiting `npx react-native start` when a session is connected. Partially reverts D49422206.
This lines back up with the original RN CLI and Expo implementations — explicitly calling `process.exit()`. We still aim to follow this up with graceful server shutdown.

Upgrade Metro dependencies to 0.79.1 in `react-native`
This includes Metro breaking changes for disabling global package resolution by default and adds features like: Haste packages, enable resolution through symlinks and passing custom customTransformOptions and customResolverOptions to bundle_build_started log event so as to refine the bundling message. It also fixes arbitrary transformation of Babel plugins during registration in `metro-babel-register` and fixes "unexpected null" crash when handling a batch of file changes and symlinks with indirections.

**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.
https://pxl.cl/3mVmR
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`.

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`.

- The current React Native version.
- "Dev server ready" on `dep_graph_loaded` event (indicating that the server is ready to receive bundle requests from devices).

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/39078
Simplifies and hardens behaviour for detecting other processes / dev server instances when running `react-native start`.
- New flow:
- Exits with error message if port is taken by another process (*no longer suggests next port*).
- Exits with info message if port is taken by another instance of this dev server (**unchanged**).
- Continues if result unknown.
- *(No longer logs dedicated message for another RN server running in a different project root.)*
- This now checks if the TCP port is in use before attempting an HTTP fetch.
Previous behaviour: [`handlePortUnavailable`](https://github.com/react-native-community/cli/blob/734222118707fff41c71463528e4e0c227b31cc6/packages/cli-tools/src/handlePortUnavailable.ts#L8). This decouples us from some lower-level `react-native-community/cli-tools` utils, which remain reused by the `android` and `ios` commands.

## Context
RFC: Decoupling Flipper from React Native core: https://github.com/react-native-community/discussions-and-proposals/pull/641
## Changes
This change:
- Links the new `react-native/dev-middleware` endpoints into the recently migrated `react-native start` command.
- Adds `react-native/community-cli-plugin` (the migrated [`cli-plugin-metro`](https://github.com/react-native-community/cli/tree/main/packages/cli-plugin-metro)) as a dependency of `react-native`, and hooks in these versions of the `start`, `bundle`, and `ram-bundle` commands via `react-native.config.js`.
Functionally, this means that the new `/open-debugger` endpoint is available on the dev server started by `react-native start` (not yet linked into any UI).
After this PR is merged, the new `community-cli-plugin` package is "linked" and we can remove `cli-plugin-metro` from `react-native-community/cli`: https://github.com/react-native-community/cli/pull/2055.

Pull Request resolved: https://github.com/facebook/react-native/pull/38795
## Context
RFC: Decoupling Flipper from React Native core: https://github.com/react-native-community/discussions-and-proposals/pull/641
## Changes
Inits new package `react-native/community-cli-plugin`. This migrates [`react-native-community/cli-plugin-metro`](https://github.com/react-native-community/cli/tree/main/packages/cli-plugin-metro) into the React Native repo, to enable faster iteration by the React Native core team. Specifically:
- This package contains several `metro` dependencies, which when removed from CLI will no longer require us to ship new CLI releases to get Metro patches and features to users.
- This package contains the `start`, `bundle`, and `ram-bundle` commands (central to the React Native development experience), for which we have incoming debugging-related changes.
- This package now **only** exports commands to be attached via a RN CLI plugin. With this move, we're aiming to **internalise** the default implementations of these dev commands within React Native — other RN CLI plugins can continue to override these, but must do so wholesale. (See also the recent fix for this: https://github.com/react-native-community/cli/pull/1999.)
In V15:
- (Microsoft feedback) Re-export `unstable_buildBundleWithConfig`, marking as unstable. This gives us a time buffer to consider how we repackage this functionality in future.
The package source has been converted from TypeScript to Flow, with a number of new `flow-typed/` defs added to meet type coverage requirements.
## To dos
- For now, we aren't removing the existing [`react-native-community/cli-plugin-metro`](https://github.com/react-native-community/cli/tree/main/packages/cli-plugin-metro) source — until later PRs consolidate this move by changing dependencies in the `react-native` package.
- **Exported API is reduced!**: I'm working with szymonrybczak to decouple references from RN CLI packages https://github.com/react-native-community/cli/pull/2021.
