Summary:
While `readline` is referenced in `packages/community-cli-plugin/src/commands/start/attachKeyHandlers.js`, this references the `node:readline` module by default. The extra package seems to have been installed and included accidentally, as the `attachKeyHandlers` file uses an export from `node:readline` that's never been present in `npm:readline`.
Since the name matches but Node.js will always prefer built-in/code modules, this dependency is dangling and can never be reached, since it's name is shadowed (as also stated in their readme). This can be reproduced by comparing `require('readline')` and `require('../../node_modules/readline')` in `packages/community-cli-plugin`. The flow types also confirm this.
This overall seems highly safe to drop.
## Changelog:
[INTERNAL] [CHANGED] - Remove shadowed and unused readline npm package from community-cli-plugin
Pull Request resolved: https://github.com/facebook/react-native/pull/49557
Test Plan:
Prior to changes applied:
```sh
$ node -e 'console.log(require("readline") === require("node:readline"))'
true
```
