Tool input consistency-check telemetry now records the tool's name and whether it's an MCP tool

What

When Claude Code detects an inconsistency in a tool's recorded input (via the tether_wire_tool_input telemetry event), the event now also includes the tool's name (toolName) and whether it came from an MCP server (isMcp), an external tool provider connected via the Model Context Protocol.

Why

This gives more context for diagnosing which specific tool, and whether an MCP-provided one, triggered an inconsistent recorded input, making it easier to track down the source of such issues.
