MCP server v2.17.0: New whoami tool, read_docs improvements, and bug fixes

New Features

whoami tool: Check which user is currently authenticated and their authentication method.

Improvements

read_docs tool: Simplified the parameters so it now accepts url or path separately instead of a combined field. Also rejects non-Sanity URLs.

list_sanity_rules tool: Fixed incorrect rule name prefixes shown in the quick reference.

System prompt: Improved instructions for the discard_drafts tool and reduced overall prompt size.
