- Remove Vagrant from dependency checks and UI; use Docker for workstation build.\n- Add WORKSTATION_VERSION ARG + OCI version label in workstation/Dockerfile; tag image as prole-workstation:<version>.\n- Add installer.workstation helpers: parse version, compose canonical docker build (auto platform flags on Apple Silicon).\n- Refactor install.py Workstation page to display/execute docker build; write logs to logs/workstation-docker-<ts>.log; update summary links.\n- Update Deploy page copy: "Build workstation Docker image".\n- Centralize footer buttons styling/layout with installer.screen.create_nav_footer and use it from install.py.\n- Update installer package docs to describe Docker-based workstation helpers.
- Add root-level installer package: config, build, workstation, deploy
- Update install.py to import from installer.*
- Ensure build/deploy use top-level proleStatus only (no prole/proleStatus)
- Keep UI/behavior intact (wizard pages, embedded console)
This commit contains only files required to run ./install.py and the new installer/* modules.
