tauri-runtime-servocat

Servo-replacement runtime for Tauri: wires html-cat, css-cat, dom-cat, layout-cat, paint-cat, net-cat, boa-cat, ecma-runtime-cat, and web-api-cat into a single rendering + scripting pipeline. v3.32.0 lights up the image pipeline that v0.7.20's accessor pack was set up for: `render_with_inline_assets` walks the DOM for `<img>` elements with `data:image/png;base64,...` src attributes, decodes each (via the `png` crate + base64 decode), and attaches a `NodeId -> DecodedImage` map to the Frame. The tiny-skia rasterizer walks the layout tree, finds each `<img>` box, and stamps the decoded pixels (premultiplied on copy, bilinear scaling to the box rect). File-path and HTTP image sources are silently skipped for now -- follow-ups will add filesystem and net-cat fetch paths. Seventh sub-crate of a Servo-replacement webview runtime targeting Tauri.
