## Summary by CodeRabbit
* **Refactor**
* Split AI initialization into separate editor, app, and shared
registries; removed legacy chat-panel and replaced it with a
component-based editor chat, updating wiring and public exports.
* Propagated server/subscription/model services into chat/playground
components and improved session lifecycle and UI composition.
* **Tests**
* Added tests for AI effect registration and chat session resolution;
extended DOM/test utilities and assertions.
* **Chores**
* Added happy-dom for runtime and test environments.
