⚡ Bolt: Optimize drw_map to use XFlush

[google-labs-jules]

⚡ Bolt: Use XFlush instead of XSync in drw_map

💡 What: Replaced XSync(drw->dpy, False) with XFlush(drw->dpy) in the drw_map function.
🎯 Why: XSync forces the client to wait for the X server to process all requests, causing a blocking round-trip. This is unnecessary for simple drawing operations and adds latency, especially when the bar is updated frequently (e.g., status updates, window title changes).
📊 Impact: Reduces latency for bar updates and other drawing operations using drw_map.
🔬 Measurement: Verified that drw.c compiles correctly. The change is a standard optimization in X11 window managers to improve responsiveness.
