🤖 Augment PR Summary

Summary: Updates the MCP (2025-11-25) JSON Schema evaluate/trace tools to accept the instance as a JSON-encoded string and parse it server-side.

Changes:

• Rename tool argument from instance to stringifiedInstance across MCP e2e suites.
• Parse stringifiedInstance in ActionJSONSchemaEvaluate_v1 before validation.
• Parse stringifiedInstance with a PointerPositionTracker in ActionJSONSchemaTrace_v1, so instancePositions refer to the parsed instance content.
• Return an MCP tool error (not JSON-RPC invalid params) when the provided string is not valid JSON.

Technical Notes:

• RPC input schemas are updated to require stringifiedInstance and document the client-stringification workaround.
• E2E assertions are updated for new argument names, new schema sizes, and updated instancePositions offsets.
