SearchBoundary

This extension adds a keyword cloud panel to the right side of Google, Bing, and Baidu search result pages. It fetches search result pages, reads article content or title/snippet text, extracts weighted keywords, and renders them as a cloud.

Core intent: even in today's AI search era (including RAG-enhanced assistants), traditional search can still hide boundary points that are easy to miss. SearchBoundary is built to help users push outward and touch the boundary of what they are actually trying to find.
