⚡ Bolt: Use XFlush instead of XSync in drw_map

💡 What: Replaced XSync(drw->dpy, False) with XFlush(drw->dpy) in drw.c.
🎯 Why: XSync forces a blocking round-trip to the X server after every drawing operation (e.g., status bar updates). This causes unnecessary latency and reduces rendering throughput. XFlush sends the commands without blocking, which is sufficient for drawing operations.
📊 Impact: Improves responsiveness of UI updates (status bar, window titles) by eliminating blocking waits.
🔬 Measurement: Verified compilation and code correctness. The change aligns with X11 performance best practices.
