-/**
- * @fileoverview FastMCP Draft-07 Compatibility Patch
- *
- * PROBLEM:
- * - FastMCP uses Zod v3 + zod-to-json-schema → outputs JSON Schema Draft 2020-12
- * - MCP clients (e.g., Augment IDE) only support Draft-07
- * - This causes "MCP server startup error" in incompatible clients
- *
- * SOLUTION:
- * Pre-convert Zod v4 schemas to Draft-07 using native toJSONSchema() before
- * passing to FastMCP, preventing it from doing its own conversion.
- *
- * TEMPORARY PATCH:
- * This will be removed once FastMCP, MCP spec, or Zod addresses the compatibility issue.
- * Tracking: https://github.com/punkpeye/fastmcp/issues/189
