refactor(@angular/cli): use main element extraction for MCP doc search
The angular.dev documenation now uses `main` elements within each page to indicate the actual content. To reduce the amount of HTML passed back in the MCP `search_documentation` tool, only the `main` element is now used instead of the entire `body` element.
