Fix MCP server compatibility with Draft-07 clients (Augment IDE, gemini-cli, gemini code assist)

  • Resolves #1284

Problem:

  • MCP tools were using Zod v4, which outputs JSON Schema Draft 2020-12
  • MCP clients only support Draft-07
  • Tools were not discoverable in gemini-cli and other clients

Solution:

  • Updated all MCP tools to import from zod/v3 instead of zod
  • Zod v3 schemas convert to Draft-07 via FastMCP's zod-to-json-schema
  • Fixed logger to use stderr instead of stdout (MCP protocol requirement)

This is a temporary workaround until FastMCP adds JSON Schema version configuration.
