New file stego_routes.py:
- register_stego_routes() mounts all encode/decode routes on the Flask app
- Async encode with ThreadPoolExecutor + progress polling
- Subprocess isolation for crash-safe stegasoo operations
- Image + audio encode/decode with full validation
- Encode result display with download
- Tools API routes (capacity, EXIF, rotate, compress, convert)
- About page with crypto documentation
Real templates (replacing stubs):
- encode.html (889 lines): full form with carrier upload, passphrase,
PIN, RSA key, embed mode selection, async progress bar
- decode.html (681 lines): decode form with credential inputs
