My first open-source contribution

I recently contributed to CursorTouch's Windows-MCP, an open-source project for AI-assisted Windows desktop automation.

The problem looked small at first. MultiEdit and MultiSelect were resolving coordinates one item at a time, repeatedly accessing the same desktop state. That meant an N+1 lookup pattern inside the hot path.

I replaced it with a bulk coordinate resolution approach. The result: 37.45% faster in a 3,000-resolution benchmark, 52.09% faster in a 35,000-resolution synthetic benchmark, and ~18% improvement in a local runtime check.

No new model. No complicated architecture. Just finding unnecessary work and removing it.

The PR was merged as my first contribution to the project: CursorTouch/Windows-MCP #219.
