Pull request overview

This PR updates Radiance’s documentation site (new home/hero content, metadata, and theme tweaks), adds a new benchmark/ workspace package for bundle-size measurement (and wires the results into docs), introduces vitepress-plugin-llms for generating llms.txt, and includes several API/internal updates in the lib/ package (pointer events args/types, quad pass shader source extraction, and GLSL conversion tweaks).

Changes:

• Add a benchmark/ workspace with build/measure scripts and generated results, and expose bundle-size data in docs via a new BundleSizeGraph component.
• Update docs home page, examples metadata, styling, and add vitepress-plugin-llms configuration to generate llms.txt.
• Update library helpers and passes: onPointerEvents now targets generic HTMLElements and returns boundingRect/center; extract quad vertex shader to a GLSL file; tweak shader conversion behavior.
