## Summary
When upgrading to `babel-plugin-react-compiler@1.0.0` in a project that
uses `zod@3` we are running into TypeScript errors like:
```
node_modules/babel-plugin-react-compiler/dist/index.d.ts:435:10 - error TS2694: Namespace '"/REDACTED/node_modules/zod/v3/external"' has no exported member 'core'.
435 }, z.core.$strip>>>;
~~~~
```
This problem seems to be related to
d6eb735938, which introduced zod v3/v4
compatibility. Since `zod` is bundled into the compiler source this does
not cause runtime issues and only manifests as TypeScript errors. My
proposed solution is this PR is to use zod's [subpath versioning
strategy](https://zod.dev/v4/versioning?id=versioning-in-zod-4) which
allows you to support v3 and v4 APIs on both major versions.
Changes in this PR include:
- Updated `zod` import paths to `zod/v4`
- Bumped min `zod` version to `^3.25.0` for zod which guarantees the
`zod/v4` subpath is available.
- Updated `zod-validation-error` import paths to
`zod-validation-error/v4`
- Bumped min `zod-validation-error ` version to `^3.5.0`
- Updated `externals` tsup configuration where appropriate.
Once the compiler drops zod v3 support we could optionally remove the
`/v4` subpath from the imports.
## How did you test this change?
Not totally sure the best way to test. I ran `NODE_ENV=production yarn
workspace babel-plugin-react-compiler run build --dts` and diffed the
`dist/` folder between my change and `v1.0.0` and it looks correct. We
have a `patch-package` patch to workaround this for now and it works as
expected.
