Pull request overview

This PR implements a JavaScript mobile bridge for WebView-based in-app messages, enabling bidirectional communication between JavaScript and native Android code using a request/response pattern.

Changes:

• Introduced BridgeMessage sealed class hierarchy with Request, Response, and Error types for structured communication
• Implemented WebViewActionHandlers to manage synchronous and asynchronous action handlers
• Added BridgeMessageValidator to validate incoming bridge messages
• Refactored WebViewInAppViewHolder to use the new bridge communication pattern with pending response tracking
