fix(compiler): add timeout and error handling for file lookup

- Add a 10-second timeout to `currentTask.get()` in `ProjectFileUtil.kt` to prevent indefinite blocking.
- Wrap `findFile` in a try-catch block in `FileInsCommand.kt` to handle exceptions gracefully and return a user-friendly error message.
