Contributions summary:Matt primarily contributed to enhancing the `chisel` project, a collection of LLDB commands for debugging iOS apps. Their work included adding new commands such as `paltrace` for tracing Auto Layout, and improving existing commands like `pviews` by adding an "upwards" option and a depth parameter. They also refactored existing code by casting types and updating uses of `UIApplication` to get the key window, and added commands to border/unborder views with ambiguous layouts.
