2d7fbd1e0d Add QR code generation to CLI and API
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

32842f6b73 Move zstandard to core dependencies
zstd is now the default compression algorithm across all frontends,
so it should always be installed with the base package.

3fd3204552 Cap RSA at 3072 bits, add zstd compression for QR codes
- 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

175362ce4c Fix async encode returning HTML errors instead of JSON
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.

2ed108f3a0 Fix decode progress - add Argon2 phase tracking
- decode.py now writes 20% "initializing" before Argon2
- decode.py writes 25% "extracting" after Argon2 completes
- DCT extraction scales from 25-70% (was 5-70%)
- Removed duplicate "loading" writes that caused backwards jumps

Progress flow: 15% reading -> 20% initializing (Argon2) -> 25-70% extracting -> 75-95% decoding -> 100% complete

f2f3e2eefc Fix decode progress - pass progress_file to library
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.

5c685cba67 Fix decode progress getting stuck at 25%
- 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

55d54717f8 Use float32 instead of float64 for DCT operations
Reduces peak memory usage by ~50%:
- ENCODE: 211 MB -> 107 MB
- DECODE: 104 MB -> 52 MB

float32 provides sufficient precision for 8-bit images
(DCT roundtrip error ~1.8e-7, well under 0.5 threshold).

Significant improvement for Pi deployments with limited RAM.
