Unbounded globbing leads to "freeze" during pod install

[ephemer]

Hello, and thank you for your work on this project! 🙂

I have been trying to understand a weird bug whereby pod install no longer works for me from RN >= 0.74. It just appears to freeze and do nothing. I left it for 30mins and nothing happened.

I finally tracked this down to the npx @react-native-community/cli config call performed during install. After some log debugging it turns out the "freeze" occurs during globbing while searching for the iOS Podfile.

We have a submodule containing native code that is very deeply nested (with its own native build system, dependencies, their build artefacts, etc.). fast-glob seems to get stuck looking in that deeply nested directory structure (maybe there's even a cycle somewhere due to symlinks – I'm not sure). In any case, it seems like the most likely case by far is that Podfile can be found in ${PROJECT_ROOT}/ios/Podfile. It seems very unlikely that it will be found in a deeply nested directory somewhere – if it will be found anywhere other than that default location in the first place.

The following diff solved my problem, and I believe it'd generally be a good idea to put an upper bound on the depth of the search:

diff --git a/node_modules/@react-native-community/cli-platform-apple/build/config/findAllPodfilePaths.js b/node_modules/@react-native-community/cli-platform-apple/build/config/findAllPodfilePaths.js
