fix(uat-tester): add missing bash permissions for worker clone and docs

Worker Mode requires git clone, git config, git pull, git checkout,
git add, git commit, git push, and uv commands in bash. These were all
missing from the frontmatter permission block, causing every Worker Mode
instance to fail immediately with permission denied on the first command.
