MCP server v2.17.1: create_version improvements and patch fixes

Improvements

create_version tool: Simplified the response and added follow-up guidance for editing version documents with patch_document_from_json or patch_document_from_markdown.

Fixes

patch_document_from_json tool: Numeric array indices are now rejected, and patch execution has been simplified for more predictable behavior.

Authentication: /token responses now include Cache-Control: no-store to prevent caching of OAuth tokens.
