feat: Lua Scripting v1

[michyaraque]

This PR introduces a major modernization and a complete Lua scripting system.

Summary

• Refactors and modernizes io_service.
• Adds a full Lua engine with exposed APIs and sandboxed execution.
• Introduces script management, menu integration, and event emitters.
• Adds map overlay support to render custom data in the map view.
• Exposes input handling (keyboard, mouse) and internal selection to Lua.
• Includes documentation and example Lua scripts.

Security

• Adds sandbox restrictions to prevent access to malicious or unknown paths.

Build & CI

• Fixes and improves CMake configuration and dependency resolution.
• Resolves Linux and Windows build issues (vcpkg, Lua, sol2, FastNoiseLite).
• Updates MSVC flags and build flow.
• Improves CI pipelines, caching, and release handling (Windows CI temporarily dropped).

Maintenance

• Version adjustments and formatting (clang-format).
• Multiple bug fixes, typo fixes, and warning cleanups.
• Updated and expanded documentation.

This lays the foundation for extensible scripting, safer execution, and improved cross-platform builds.
