## Description

Bridges the dnSpy/ILSpy .NET reverse engineering ecosystem with language models through a modular C# architecture. Provides tools for listing types, decompiling methods with overload targeting, inspecting raw IL bytecode, searching string references, and performing binary patches (string replacement and NOP insertion) with automatic backup creation. Supports navigation-friendly output with metadata tokens for direct dnSpy jumps and exposes assembly resources through a cache-driven resource system.
