tauri-runtime-servocat 0.5.0

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. v0.5.0 adds an IPC bridge so JS scripts can call host commands via `__TAURI__.invoke(cmd, ...args)`, and back-propagates scripted DOM mutations into layout via `web_api_cat::extract_document`. tauri_runtime::Runtime trait impl is the remaining committed deliverable. The Servo no-AI policy disqualifies upstream contribution; this is the AI-built parallel.

//! Servo-replacement runtime for Tauri.
//!
//! v0.1 shipped the headless pipeline + script driver; v0.2 added a
//! tiny-skia rasterizer ([`render_to_pixels`]); v0.3 added cosmic-text
//! shaping + swash glyph raster so `FillText` commands render real
//! text; v0.4 added a winit + softbuffer window via [`run_window`] and
//! a runnable demo binary; v0.5 adds an IPC bridge ([`HostCommands`])
//! plus DOM-mutation back-propagation via [`run_script_with_backprop`]
//! so scripted mutations re-render in the window.
//!
//! # Example
//!
//! ```
//! # fn main() -> Result<(), tauri_runtime_servocat::Error> {
//! use tauri_runtime_servocat::{Viewport, render, render_to_pixels, run_script};
//!
//! let frame = render(
//!     "<html><body><p>hello</p></body></html>",
//!     "p { background-color: red; padding: 8px; }",
//!     Viewport::new(800, 600),
//! )?;
//! assert!(!frame.display_list().is_empty());
//!
//! let pixels = render_to_pixels(&frame, 800, 600);
//! assert_eq!(pixels.rgba().len(), 800 * 600 * 4);
//!
//! let scripted = run_script(
//!     "<html><body><p id='g'>hi</p></body></html>",
//!     "",
//!     "document.getElementById('g').textContent",
//!     Viewport::new(800, 600),
//! )?;
//! assert_eq!(format!("{}", scripted.script_value()), "\"hi\"");
//! # Ok(())
//! # }
//! ```
