Workflow: threads manager

The user runs many Claude threads at once on one repository, and asks this thread to keep track of them. Each check answers four questions:

1. What landed on main since the last check, and does every change have its changelog entry with its pictures?
2. Is live healthy and current, or is it broken or behind main?
3. What is each thread doing: running, finished, cut off mid-task, or waiting on the user?
4. What can be archived, and what needs the user?

If this skill has a references/<project>.md for the current project, read it. Read the project's AGENTS.md first on every check, because other threads keep changing the rules (the live host, the changelog format, the size limits). Where AGENTS.md and this skill disagree, AGENTS.md wins.
