MCP server v2.14.0: Tool titles, schema validation, and improved tool annotations

New Features

Tool titles. All tools now include human-readable titles for better display in MCP clients.

Schema validation. We're gradually rolling out schema validation for create_documents_from_json and patch_document_from_json, which ensure that requested changes conform to the deployed schema.

Fixes

read_docs tool. Improved input validation and path handling.

Tool annotations. Added missing annotations to tools that were lacking them, helping MCP clients correctly identify read-only vs. destructive operations.

Input validation. Standardized project ID and dataset name validation across tools.
