- 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,
cutting install time from 20+ minutes to ~2 minutes.

- 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.
