Pull Request Overview

Adds initial SVG support by defining SVG-specific value types, parsing logic, style properties, layout integration, and rendering pipelines.

• Introduces core SVG value types and parsers (Paint, ViewBox, SVGProps) in vaev-values.
• Extends the style system with SVG presentation attributes and inheritance in vaev-style.
• Integrates SVG elements into layout (vaev-layout) and painting (vaev-layout/paint.cpp).

src/vaev-values/svg.h:1

• New SVG parsing and value types (e.g., Paint, ViewBox, SVGProps) were added without corresponding unit tests. Consider adding tests for ValueParser<Paint>, ViewBox::repr, and default SVGProps initialization to validate correctness.

src/vaev-style/decls.h:174

• [nitpick] The function name wrapPathAsCSSStyle is ambiguous—consider renaming to something like wrapSvgPathFunction or wrapSvgPathAsCssFunction to clarify that it wraps SVG path data into a CSS path() function syntax.
