- Check /login redirect to /setup instead of homepage redirect
- Use logout link presence to verify login success (encode/decode are public)
- Add -c flag to save cookies during homepage check
The smoke test was passing login even when not logged in because
encode/decode links are visible to everyone.

- Create venv with explicit pyenv Python path
- Build jpegio INTO venv (not globally)
- Add python3-dev to apt dependencies

This fixes the issue where jpegio was built globally, then pip
tried to reinstall unpatched jpegio from PyPI into the venv.

- 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.
