Implement a VS Code Sweeper agent-ready issue — fetch the sweeper's review record from its state repo, implement the change in the current vscode checkout from the review's brief (an implement-ready record) or from an approved sweeper-plan file, validate the diff against it, and — after the maintainer has reviewed the changes in their editor — open a draft PR. Use ONLY when the request explicitly asks for the sweeper — "sweeper-implement", "sweeper", "vscodesweeper", a sweeper record, an agent-ready issue, or a sweeper brief — or asks to implement a sweeper plan ("implement plan <n>", a `.sweeper/plans/issue-<n>.md` file). Do NOT use for a plain "fix this issue" request that doesn't mention the sweeper; fix those directly with your normal tools instead.
