⚡ Bolt: Remove synchronous X call in drawing path

💡 What: Removed XSync(drw->dpy, False); from drw_map in drw.c.
🎯 Why: XSync forces the client to wait for the X server to process the request, creating significant latency (network round-trip + context switch) for every drawing operation. This is a bottleneck for UI updates like the status bar.
📊 Impact: Reduces latency for all drawing operations using drw_map. In high-frequency update scenarios (e.g., animations, typing), this prevents the window manager from blocking on the X server.
🔬 Measurement: Verified that the project builds correctly with make clean && make. Visual verification (via code review) confirms that event loop processing will implicitly handle flushing, making XSync redundant.

Removing `XSync` from `drw_map` eliminates a blocking round-trip to the X server
on every draw operation. This improves responsiveness and reduces latency during
frequent updates, such as bar redrawing or mouse interactions. The X11 protocol
guarantees order of operations, so `XCopyArea` remains safe without explicit
synchronization.
