IDEAS: okgame (C++) Improvements

1. Build System & Toolchain

Vcpkg / Conan Integration: The lib/ folder contains dozens of deeply vendored submodules (Boost, SDL, Poco, libpng, etc.). Transitioning to a package manager like vcpkg or Conan would simplify the CMake script immensely and speed up native build times.
CMake Modernization: Upgrade all CMakeLists.txt to strictly use target_link_libraries (Modern CMake) rather than legacy include_directories and global variables to prevent dependency bleeding.

EnTT / ECS: The current hierarchy (EnginePart, Entity, Map) is highly object-oriented. Migrating game objects to an Entity-Component-System (like EnTT) would vastly improve cache locality and iteration speed, especially for complex RPG maps.
Vulkan / SDL3: The rendering is currently bound to OpenGL (Core Profile). Preparing the abstraction layer to target Vulkan via SDL3's GPU API would future-proof the engine.

Sol3 / Sol2: The engine uses manual Lua C-API stack manipulation. Integrating Sol2 or Sol3 would provide type-safe, elegant C++17 bindings for the Lua scripts.
Hot Reloading: Implement a directory watcher (efsw or similar) to hot-reload Lua puzzle scripts and shaders while the engine is running.

miniaudio: Replace SDL_mixer or heavily patch it with miniaudio.h. miniaudio is a single-header library that provides incredibly low-latency mixing, which is critical for frame-perfect puzzle game sound effects.

Unified Build: If okgame achieves a clean SDL3/Vulkan build, an Emscripten target could be revived. This would allow the absolute native 1:1 C++ code to run in the browser, potentially deprecating bobsgameweb if it runs efficiently enough.
