Added comprehensive README.md documentation to every project and subfolder in the solution. Each README describes the purpose, key files, structure, dependencies, and design patterns for its area. This improves codebase navigability and maintainability, and includes a maintenance note to keep docs in sync with future code changes.
Introduce AcDynamicMethodRegistry<TAttribute> for efficient, static caching and lookup of SignalR methods by messageTag and type. Replace per-instance method lists with a high-performance registry, update all registration and invocation logic to use the new approach, and make method metadata caching type-based and immutable. Also expand Bash permissions in settings.local.json and rename ReadVarUIntFromBytes for consistency. This improves performance, maintainability, and code clarity for dynamic SignalR method invocation.
