Swap `fs` with `node-graceful-fs` for more robust cross operating system support

After upgrading from v1.0.0-beta.21 to v1.0.0-beta.23 I started receiving the following error:

⌛️ ZenStack CLI v1.0.0-beta.23, running plugins

An unexpected error occurred:
[Error: EMFILE: too many open files, open 'PROJECT_DIR/node_modules/.zenstack/zod/objects/ImagePredictionUncheckedCreateWithoutPhotoInput.schema.js'] {
  errno: -24,
  code: 'EMFILE',
  syscall: 'open',
  path: 'PROJECT_DIR/node_modules/.zenstack/zod/objects/ImagePredictionUncheckedCreateWithoutPhotoInput.schema.js'
}

An unexpected error occurred:
[Error: EMFILE: too many open files, open 'PROJECT_DIR/node_modules/.zenstack/zod/objects/ImagePredictionUncheckedCreateWithoutPhotoInput.schema.js'] {
  errno: -24,

}

Unfortunately, a more detailed error stack isn't included, but the error suggests OS open file limit reached.

The lib node-graceful-fs is a drop-in replacement for fs and automatically handles this category of issue without having to modify /etc/security/limits.conf on linux or god knows what for windows

Also, if the source of this error is tsc or another external tool, OS settings would be required and the node-graceful-fs recommendation would be irrelevant

Thanks for pointing me to that package! I'll look into it. The problem probably likes in "ts-morph" (used to do TS generation and emit JS files).

Resolving for now. Please reactivate if you still run into it.
