- Replace monolithic build flow with three operating modes: pull (default), local-build, publish
- Add version.txt for image tagging and multi-platform builds via buildx (--publish)
- Switch builder to tarball-based Quarto install for better cross-platform reliability
- Update docker-compose.yml and jupyterhub_config.py to use environment variables for image names, defaulting to registry images
- Refactor start-jupyterhub.sh: modular functions for image management, clearer flag handling and error messages
- Simplify Readme.md with structured tables instead of dense paragraphs, clarify data persistence and R package workflow
- Added --rebuild-builder, -student, hub flags to start-jupyterhub.sh for granular Docker rebuilds
- Updated check_if_image_needs_rebuild to accept per-image force flag and propagate no-cache option
- Added libuv1-dev dependency in Dockerfile.builder (likely for quarto or R runtime)
- Rewrote install_quarto_deps.R to:
a) Manually parse library()/require() and remotes::install_git/github calls
b) Distinguish between quarto-required packages (must reside in persistent target_lib)
c), CRAN and git/github dependencies
d) Install with robust error handling, skipping unavailable packages
- Removed dependency on attachment package for scanning
