magpie-setup-upstream-fix

Turn a framework bug or quirk the agent hit while running a Magpie skill or tool into a fix PR against apache/magpie — one PR per issue. First confirms the problem is a framework defect (not a local misconfiguration or a stale snapshot), then searches apache/magpie for an existing issue or PR that already covers it, and only proposes a new fix PR when none exists — otherwise it points the user at the pending one.
