Godot Engine — visual shaders

The shared engine foundation includes a native port of Godot Engine’s visual shader node catalog and code-generation semantics. This covers shader inputs, constants, texture sampling, arithmetic and mathematical nodes. Godot’s source is used as a port/reference rather than vendored wholesale.
