Implements a WebGPU/WGSL backend for EigenScript enabling GPU acceleration in the browser: Language changes: - Add 'gpu:' block syntax to lexer (GPU token) - Add GPUBlock AST node to parser for grouping GPU operations WGSL Backend (wgsl_backend.py): - GPU-lite EigenValue struct (value + gradient only, 8 bytes) - Tiled matrix multiplication kernel with shared memory - Parallel reduction kernels for dot product and norm - Element-wise operation kernels (add, sub, mul, div, scale) - JavaScript/WebGPU runtime for browser integration GPU-lite EigenValue model: - Unobserved GPU computation stays lean (f32 value + gradient) - Observation triggers device→host sync + full geometric promotion - Fits EigenScript's observer-effect semantics Includes GPU playground demo and 18 passing tests.
