Most updates just need git pull + systemctl restart since we use
editable pip installs.

The code now explains itself like a friend teaching you crypto:
- DCT module: Why mid-frequency? What's QIM? Why is scipy being weird?
- Steganography: How LSB actually works with visual examples
- Crypto: The multi-factor security model with ASCII art diagrams
Also adds kickoff-pi-test.sh - one command to flash, wait, setup, test.
No more manual steps between flashing and seeing if it works.
Comments should teach, not just describe. If you're reading the code
trying to understand how DCT steganography works, these comments
should actually help. Novel concept, I know.

- Combined tarball includes pyenv Python 3.12 + venv with all deps
- Downloads from GitHub releases by default (~50MB)
- Reduces install time from 20+ min to ~2 min
- Add --no-prebuilt / --from-source flags to force compile
- Update BUILD_IMAGE.md with tarball creation instructions
- Rename tarball: stegasoo-pi-arm64.tar.zst (was venv-only)

- USE_PREBUILT=true by default, downloads from GitHub releases
- Add --no-prebuilt / --from-source flags for manual builds
- Update estimated time: ~2 min vs 15-20 min from source
- Update help text with new options
Fresh Pi installs now download pre-built venv automatically,

- Move repo clone to step 4 (before pyenv) to check for tarball early
- Set USE_PREBUILT flag immediately after cloning
- Python compile only happens if not already installed (fallback)
- Better progress messages during install
This ensures pre-built venv detection happens before expensive
Python compile step, and skips compile entirely on repeat installs.
