State existed in the lifecycle table and the enum but no verb, route,
or service path ever set it. Removing dead state. If we need
problem-task isolation later we'll add it explicitly with a verb.
The 'lib/' rule (intended for Python virtualenv at repo root) was matching panel/src/lib/, hiding the entire panel API client + utility tree from git. Anchored Python build-artifact rules to the repo root with a leading slash so they only match at the top level. Adds 28 panel/src/lib files that should have been tracked from day one.
