Expand description

Find the AgentMux window label whose top-level HWND contains the cursor position. Excludes the dragged window itself (landing on the dragged window’s strip would be a no-op merge). Takes the browsers lock guard from the caller so we don’t re-acquire on the WM_MOUSEMOVE hot path.
