Use url fragment schema for deep link URIs, borrowing from URL/PDF schemas. E.g file:///path/to/file.txt#line=<line_no>&#page=<page_no> Compute line number during (recursive) markdown entry chunking. Test line number in URI maps to line number of chunk in actual md file. This deeplink URI with line number is passed to llm as context to better combine with line range based view file tool. Grep tool already passed matching line number. This change passes line number in URIs of markdown entries matched by the semantic search tool.
