fix(core, cli): await outputStream.end() to prevent race conditions
This commit fixes a critical race condition where
was called synchronously without being awaited. This led to potential file
truncation or EBUSY errors on Windows when attempting to manipulate the file
immediately after the call.
Additionally, this change removes fixed wait times (`setTimeout`) that
were previously used in test files as a band-aid.
