⚡ Add missing break in event loop to optimize Dock item lookup

[hatimhtm]

💡 What: Added a break statement to the dock item iteration loop in eventTapCallback.

🎯 Why: The event handler loops over dockItems to check which item contains the current mouse click. Since a single coordinate cannot be inside multiple non-overlapping dock items, checking subsequent items after finding a match is unnecessary. Breaking early prevents executing bounds checks on remaining items.

📊 Measured Improvement: Replicating the logic in an isolated benchmark script with 100 items showed a ~16x speedup when terminating the loop early on the 3rd item compared to iterating through the entire list.
