tauri-runtime-servocat 1.7.0

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. v1.7.0 adds per-window `WindowFlags` bookkeeping so `is_enabled` / `is_maximizable` / `is_minimizable` / `is_closable` / `is_always_on_top` / `is_focusable` round-trip real values from their matching setters; webview `bounds` / `position` / `size` queries now return tracked values updated by `set_bounds` / `set_size` / `set_position`. The Servo no-AI policy disqualifies upstream contribution; this is the AI-built parallel.

//! v1.5 demo: install a `WebviewIpcHandler` on a webview (the
//! Tauri-side hook that a real app's `tauri::Builder::invoke_handler`
//! plugs into) and fire it from a worker thread via
//! [`ServocatWebviewDispatch::send_ipc`].  The handler prints the
//! request and then sends a result string back through the webview's
//! `eval_script` channel, the way Tauri's command system delivers a
//! response to JS.
//!
//! Run with `cargo run --bin demo_tauri_ipc_handler`.  Close the
//! window to exit.
