tauri-runtime-servocat 2.1.0

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. v2.1.0 applies the webview's tracked zoom factor visually: the softbuffer compositor samples the rasterized frame with `1/zoom` step so `set_zoom(1.5)` makes each source pixel cover a 1.5x1.5 destination block (zoom in, top-left anchored). Bitmap nearest-neighbour scaling -- crisp re-rasterized text waits on a pipeline-side layout-with-scale-factor pass. The Servo no-AI policy disqualifies upstream contribution; this is the AI-built parallel.

//! v1.7 demo: drive the previously-no-op `WindowDispatch` state
//! getters (`is_enabled`, `is_maximizable`, `is_minimizable`,
//! `is_closable`, `is_always_on_top`) plus `WebviewDispatch::bounds`
//! / `position` / `size`, round-tripping through `WindowFlags` and
//! webview-bounds bookkeeping in the `AppHandler`.
//!
//! Run with `cargo run --bin demo_tauri_state_tracking`.  Close the
//! window to exit.
