docs(offloader): update retrieval tool docs to reflect Python parity

The Python SDK now supports the same targeted retrieval parameters
(pattern, line_range, context_lines) as TypeScript. Remove the
SDK-specific tabs for the feature description and show unified
examples.

 The plugin includes a `retrieve_offloaded_content` tool that lets the agent fetch offloaded content by reference, returning it in its native format — text as a string, JSON as a JSON block, images as image blocks, and documents as document blocks. This tool is registered by default.
 
+The retrieval tool supports targeted retrieval through optional parameters, so the agent can search and filter offloaded content without loading it entirely back into context.
