CLI generate command:
- --qr <file.png|jpg> to save RSA key as QR image
- --qr-ascii to print ASCII QR code to terminal
API endpoints:
- POST /generate-key-qr - generate QR from key_pem
- Supports png, jpg, and ascii output formats
- Uses zstd compression by default
- Added has_qrcode_write to /capabilities
Core:
- generate_qr_code() now supports jpg/jpeg output format
- New generate_qr_ascii() for terminal display

zstd is now the default compression algorithm across all frontends,
so it should always be installed with the base package.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- RSA key size capped at 3072 bits (4096 too large for QR codes)
- Added zstd compression for QR code RSA keys (better ratio than zlib)
- New prefix STEGASOO-ZS: for zstd, backward compatible with STEGASOO-Z: (zlib)
- Added zstandard dependency to web/api/compression extras
- Updated all docs, CLI options, and web UI to reflect 3072 max
- Version bump to 4.2.0

When encode form was submitted in async mode, validation errors
returned HTML (render_template) instead of JSON, causing
"Unexpected token '<'" parse errors in the browser.
Added _error_response() helper that returns JSON in async mode
and HTML flash in sync mode.

Worker was writing 25% then calling decode() without progress_file,
so library couldn't update progress. Now passes progress_file through
so library's extraction/RS-decode progress updates work.

- Reduce PROGRESS_INTERVAL from 2000 to 500 for responsive updates
- Scale extraction progress to 5-70% range
- Add progress updates before/after RS decode (75% and 95%)
- RS decode is the slow part, now visible in progress

- Remove pv (showed read progress, not write progress)
- Use dd status=progress for actual write progress
- Reduce block size to 1M (better for slow SD cards)
- Remove conv=fsync (sync at end instead, faster)
