Adds a new function for executing MCP tools with automatic handling of large results. When tool output exceeds the configurable threshold, data is stored as an attachment and LLM receives only a summary. Features: - Auto-injection of attachment data into subsequent tool calls - Configurable threshold (env or per-call), data arg name, attachment key - Proper handling of user-provided values (no overwriting falsy values) - 19 unit tests covering all scenarios Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
