New viewer-webgl package that renders perspective views on the GPU. Three chart types (scatter, line, treemap), each with custom GLSL shaders, chunked Arrow streaming, and a shared buffer pool for GPU memory reuse. Handles axis/legend/tick layout, gridline rendering, and zoom/pan interaction. Hooks into the viewer's streaming draw lifecycle. Adds the webgl-example app and registers the package in the workspace and setup script. Signed-off-by: Timothy Bess <timbessmail@gmail.com>
