    Worker function that directly puts results in a queue rather than using futures.

    This is the current active S3 worker used in production:
    - Downloads S3 file to local temp directory
    - Processes the file using extractors
    - Puts results directly into a multiprocessing.Queue
    - Uses dynamic timeouts (45min for decompile, 20min for analysis)
    - Designed for multiprocessing.Process() with queue-based result collection
    - Provides better error handling and timeout recovery
    - Used by _process_files_streaming() method for S3 file processing
