Re-install graphql plugin in workspaces

Editor assessment

The subject states the remedy concretely: the GraphQL plugin is reinstalled in workspaces. The operation and the affected objects are both named, so the diff is unnecessary for comprehension. The fix type matches a defect correction. No scope is present, though the workspace area is identified. The body repeats the headline in one squashed line, harmless filler on a small change. No footers appear. The gerund-free imperative phrasing is clean, and the message is clear, targeted, and self-sufficient for its size.
