Functions

candidate_label_under_cursor_locked 🔒

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.

start_tear_off_tracking

Spawn a hook thread for the duration of a tear-off gesture. Returns Ok once the hook is installed; the thread runs in the background until WM_LBUTTONUP arrives or stop_tear_off_tracking is called.
