[phact]

This pull request includes several updates to the CI/CD workflows and Docker build configurations to improve reliability and maintainability. Key changes include adding environment setup steps, enhancing error handling, unifying version update scripts, and modifying Dockerfile mounts and paths.

Workflow Improvements:

• Environment Setup: Added a new step to set up the environment in the docker-build.yml workflow. (.github/workflows/docker-build.yml)
• Error Handling: Enhanced error handling for version extraction in the docker-build.yml workflow. (.github/workflows/docker-build.yml)

Dockerfile Updates:

• Mounting Project Files: Updated the Dockerfile to mount additional project files required for building with uv. (docker/build_and_push_base.Dockerfile) [1] [2]
• Virtual Environment Path: Modified the Dockerfile to use the virtual environment at the root due to workspace requirements. (docker/build_and_push_base.Dockerfile)

Script Enhancements:

• Unified Update Script: Introduced a new script update_pyproject_combined.py to handle both base and main updates in a single run. (scripts/ci/update_pyproject_combined.py)

Other Changes:

• Shell Options: Updated the shell options in the nightly_build.yml workflow to improve script robustness. (.github/workflows/nightly_build.yml)
• Workflow Cleanup: Commented out the unsupported Docker build step in the release_nightly.yml workflow. (.github/workflows/release_nightly.yml)
