Add support for polyhedron() and text() primitives (inspired by OpenSCAD)

[aquaratixc]

Hello,

I'd like to request the addition of two powerful geometric primitives commonly found in OpenSCAD:

polyhedron() — for creating custom 3D shapes defined by vertices and faces.
text() — for generating 3D text from a given string, font, and size.
These features are essential for advanced modeling workflows, especially when working with complex or procedurally generated geometry. For example:

polyhedron() enables precise control over custom mesh structures (useful in CAD, architecture, or parametric design).
text() allows embedding readable labels, names, or annotations directly into 3D models without needing external tools.
Adding these primitives would significantly enhance the expressive power and flexibility of the project, bringing it closer to full OpenSCAD-like functionality while maintaining its own unique strengths.

Thank you for considering this enhancement!
