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.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/39059
## 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.
