Add git, gh, openssh-client, curl, and sudo to the computer image with a docker smoke test. Mount deployment-owner project workspacePath at /home/rakazo/project, align /home/rakazo file paths with shell, and resolve default branch from origin/HEAD. Inject the owner GitHub token from encrypted deployment settings only into project computers; enforce branch-only push, block force-push, and require approval before the first push or gh pr in a run. Add runaway guards (tool fuse and stall pause), collapse live narration, fix streaming progress merge, DE run strings, and Lead as the project main Oo name. Fix evo-deploy test flake.
