feat: Add Chrome extension template with WXT and Base44

[kfirstri]

Note

Description

This PR introduces a new Chrome extension template that combines the WXT framework with Base44 backend integration. The template provides a fully functional bookmark manager extension featuring AI-powered search capabilities, demonstrating how to build modern browser extensions with Base44's data storage and agent capabilities. Users can save bookmarks, browse them with a clean React UI, and search using natural language queries powered by Base44 agents.
