rnx-kit treeShaking is removing necessary files from react-native-reanimated

[adamivancza]

Description

I'm working on adding rnx-kit bundling in our app and noticed that after I bundle our app the app crashes. After some digging I opened up an issue inside rnx-kit: https://github.com/microsoft/rnx-kit/issues/2767. After some further digging I noticed that the sideEffects seems incorrect to me inside packages.json: https://github.com/software-mansion/react-native-reanimated/blob/main/package.json#L184 These paths are not existing for react-native so I think some necessary files are getting stripped out as part of tree shaking. After I changed this to a plain true locally our app is working fine. Any idea what further paths we need to include for react native?

Steps to reproduce

1. Create an app, add an animation
2. Enable rnx-kit bundling with treeShaking
3. Create a release version of the app with the bundle created by rnx-kit
4. The app is crashing

Hey! 👋

The issue doesn't seem to contain a minimal reproduction.

Could you provide a snack or a link to a GitHub repository under your username that reproduces the problem?
