Diffing mode

This task focuses on bringing binary diffing directly into Cutter by integrating the core capabilities of rz-diff into its interface. Since binary diffing is a common reverse engineering workflow, the goal is to let users select and compare two binaries within Cutter itself rather than relying on external tools. The project would involve building a user-friendly file selection interface for choosing the binaries to compare, then visually presenting detected differences across Cutter’s major analysis views, including the hexadecimal view, disassembly view, graph view, and pseudocode view, so analysts can inspect structural and behavioral changes seamlessly in one environment.
