🧹 Remove 'any' type usage in EditorController

[google-labs-jules]

🎯 What: Removed the 'any' type cast when passing document.hostBridge to WebviewMessageHandler and updated the constructor parameter to strictly use the HostBridge type.
💡 Why: Improves type safety and code readability by explicitly specifying the expected type instead of falling back to 'any', making the bridge dependencies clearer.
✅ Verification: Verified by running type checking with bun build and executing unit tests for webviewMessageHandler via npx tsx.
✨ Result: The codebase is cleaner and stricter with respect to HostBridge usage without modifying the runtime behavior.
