web-api-cat 0.7.9

Bindings between boa-cat (JS engine) and the DOM (html-cat tree) plus fetch (net-cat). v0.7.9 ships `new Event(type, options)` and `new CustomEvent(type, options)` constructors as global bindings (and the legacy bare-call forms, since boa-cat 0.7.2's NativeFn-as-constructor path supports both). Dispatch now decorates the user's event Object in place rather than creating a fresh copy, so post-dispatch reads of `defaultPrevented` / `target` / `currentTarget` on the caller's reference reflect what happened during the bubble walk. Seventh sub-crate of a Servo-replacement webview runtime targeting Tauri.
