Remove direct writer.close() call

Stop capturing and closing the WriteGear writer from the shutdown path. The change removes the local `writer` assignment and the try/except block that called `writer.close()`, avoiding potential double-close/race-condition exceptions during shutdown. The recorder closure is handled by the finally block calling _finalize_writer
