Fix: Handle window size in native layer

[freakdaniel]

Description

This PR fixes the window size constraint properties so MaxHeight, MaxWidth, MinHeight, and MinWidth are retrieved from the native layer instead of being stored separately in managed C# state

Type of Change

• Bug fix (non-breaking change fixing an issue)

Changes Made

• Added native GetMaxSize and GetMinSize APIs and wired them through the export and C# interop layers
• Updated InfiniFrameWindow to read min/max size constraints from native state, with startup parameter fallback before initialization
• Removed managed-side caching of min/max window size constraints from the window builder and window extension methods
• Implemented native min/max size getters for Windows, Linux, and macOS, and ensured Linux keeps its internal constraint values in sync when setters are called

Related Issues

Closes #79
