How to reproduce the issue with native watchers

1. Clone the repo
2. Install the dependencies (yarn install)
3. Run yarn run dev:rspack
4. You should see one TypeScript error in the terminal. Change

   const variable: string = 123;

   to

   const variable: number = 123;

   in ./src/index.ts. The TypeScript error will be fixed, but the same error will still be shown in the terminal.
5. Restart yarn run dev:rspack. The error will no longer be shown. Now change

   const variable: number = 123;

   to

   const variable: string = 123;

   in ./src/index.ts. There should be a TypeScript error again, but it does not appear in the terminal.
6. Restart yarn run dev:rspack. You should now see one TypeScript error in the terminal.

If we change experiments.nativeWatcher to false - steps 5 and 6 will not reproduce.

Expected behavior

• After fixing the error (step 4), the error message should disappear from the terminal.
• After introducing a new error (step 5), the error message should immediately appear in the terminal without requiring a restart.

Expected behavior

• After fixing the error (step 4), the error message still remains in the terminal.
• After introducing a new error (step 5), the error message does not appear until the process is restarted.
