Move bip39-words.txt into package data directory and use

The CLI api commands were using a hardcoded path to find frontends/
which didn't work when installed as a package. Now tries both:
- Development: .../stegasoo/frontends
- Installed: .../site-packages/frontends

TLS Support:
- Auto-generates self-signed certs on first run
- Certs include localhost, local IPs, hostname.local
- Stored in ~/.stegasoo/certs/
CLI Commands:
- stegasoo api keys list/create/delete

New package in aur-cli/ for CLI-only installation:
- Installs [cli,dct,compression] extras only
- No flask/gunicorn/fastapi/uvicorn/pyzbar dependencies
- 68MB vs 79MB for full package
- Conflicts with stegasoo-git (can't install both)

Port Web UI image tools to CLI for parity:
- compress: JPEG compression with size reduction stats
- rotate: Rotation and flip with jpegtran for JPEGs (DCT-safe)
- convert: Format conversion between PNG, JPG, BMP, WebP
Rotate tool supports flip-only operations without rotation.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
CLI encode:
- Auto-detect output format from extension (.jpg → DCT mode, .png → LSB)
- Default to JPEG output for JPEG carriers (preserves DCT benefits)
- Pass embed_mode and dct_output_format to encode function
jpegtran fix (critical for rotation fallback):
- Remove -trim flag which was dropping edge blocks and destroying stego data
- Remove -perfect flag which fails on non-MCU-aligned images
- Plain jpegtran without flags works correctly for lossless rotation
This enables: encode → external rotation → decode to work correctly.

EXIF Viewer:
- Card-based grid layout with categories (Camera, Image, Date/Time, Exposure, GPS, Other)
- Icons for each category
- Truncation for long values with full value on hover
Tools UI:
- Reduced padding from 1.25rem to 0.5rem on all tool panels
- Smaller fonts for labels (0.55rem) and values (0.7rem)
- Compact headers and action buttons
- Tighter grid gaps and card padding

DCT steganography improvements:
- Add _apply_exif_orientation() to fix portrait photos encoding rotated
- Add _jpegtran_rotate() for lossless JPEG rotation preserving DCT data
- Add rotation fallback in extract_from_dct() - tries 0°, 90°, 180°, 270°
- Quick header validation to skip invalid rotations efficiently
- Fix: wrap debug.print in try/except to prevent extraction failures
Web UI rotate tool:
- Use jpegtran for JPEGs (lossless, preserves DCT steganography)
- Fall back to PIL for non-JPEGs
- Dynamic UI shows "DCT Safe" for JPEGs, warning for other formats
This enables the workflow: encode → compress → rotate → decode
Rotated stego JPEGs can now be decoded by trying all orientations.

Pentax and other cameras have binary EXIF fields (MakerNote, etc.) that
contain raw bytes. The previous code used errors="replace" which still
produced strings with replacement characters that broke JSON parsing.
Now properly detect non-printable binary data and display as
"<N bytes binary>" instead.

Only remove dictionary entries for turbo/mozjpeg versions in setup.py
(they need cmake-generated headers). Keep the if blocks intact - they
safely evaluate to False for standard libjpeg versions.

APIs changed between libjpeg versions, so each version directory
needs its matching headers:
- 6b gets 6b headers
- 7 gets 7 headers
- 8-8d get 8d headers
- 9-9f get 9f headers

The setup.py has broken include_dirs that reference 'jpeglib/cjpeglib'
but the source files are in 'src/jpeglib/cjpeglib'. Create a symlink
to fix the include path resolution.

The PyPI source tarball is missing both jpeglib's own headers
(cjpeglib_common.h, etc.) and libjpeg headers. Clone from GitHub
which has the jpeglib headers, then download libjpeg headers.

jpeglib has no pre-built ARM64 wheel and the source tarball is missing
libjpeg header files. This adds a workaround that downloads the official
libjpeg headers before building.
- Add rpi/patches/jpeglib/install-jpeglib-arm64.sh helper script
- Update setup.sh to download headers when building from source
- Downloads headers for libjpeg 6b, 7-9f, turbo, and mozjpeg versions

- Rewrite setup.sh to use system Python instead of pyenv
- Add Python version check (3.11-3.14 supported)
- Remove jpegio build steps (jpeglib installs cleanly via pip)
- Simplify prebuilt tarball (just venv, no pyenv)
- Reduce install time: 5-10 min from source (was 15-20 min)
- Update README.md and BUILD_IMAGE.md accordingly

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.
