- Add reedsolo library for RS error correction (32 symbols = 16 byte correction per 223-byte chunk)
- Protect entire payload (header + data) with RS encoding
- Store 3 copies of length header with majority voting for robustness
- Handle RS chunking overhead (varies based on data size)
- Update capacity calculation to account for RS overhead (24 bytes prefix + variable RS overhead)
- Add RS to dct, web, and api optional dependencies
- Update about.html with v4.1.0 Reed-Solomon feature
- Update module docstring
This fixes DCT decode failures with certain carrier images that have
uniform areas causing unstable DCT coefficients.

- Fix block calculation mismatch in DCT extract (use original dimensions)
- Change default dct_color_mode from "grayscale" to "color"
- Update DCT test to use noise image instead of solid color
- Remove debug logging from encode/decode paths
The block calculation fix ensures extract uses the same block positions
as embed for images whose dimensions aren't divisible by 8. This was
causing decode failures on the Pi web UI with 1195x671 images.
Color mode is now the default since it preserves the original image
colors. The test fixture now uses a random noise image because solid
color images cause coefficient drift during YCbCr/RGB conversion that
can corrupt embedded data.

Debug prints need file=sys.stderr to appear in journalctl output.
Encode route was fixed but decode was still using plain print().

- Add required -r/--reference option to encode command
- Add required -r/--reference option to decode command
- Replace stub implementations with actual library calls
- CLI now properly encodes and decodes messages/files
- Fix smoke test form field names and add proper redirect handling
The CLI encode/decode were stubs that didn't actually work.
Now they properly use the stegasoo library functions.
