Add an informational panel and mesh-outline toggle to the cloth demo, plus richer physics and shading. The cloth component now provides AlgorithmInformation to an <app-information> view and a toggleMesh() that flips the mesh wireframe. Constraint generation was extended with four diagonal phases (constraintsP4..P7) and the solver loop was generalized to iterate solver pipelines, improving parallel XPBD constraint handling. The WGSL vertex/fragment shaders were updated to pass world positions, compute normals, add simple lighting and a grid-based base color. Also update information template/model to support optional translated entry names and expand i18n (DE/EN) with cloth texts and a Docker key.
