[Go] Panic when parsing jsonschema

[malyusha]

My MCP external server (python fast mcp) has a tool with the following JSON input schema:

{
      "properties" : {
        "query" : {
          "title" : "Query",
          "type" : "string"
        },
        "domain" : {
          "anyOf" : [ {
            "type" : "string"
          }, {
            "type" : "null"
          } ],
          "default" : null,
          "title" : "Domain"
        }
      },
      "required" : [ "query" ],
      "title" : "get_coding_contextArguments",
      "type" : "object"
    }

There's a panic at plugins/googlegenai/gemini.go#464 when it tries to read non-existing property type.
The thing is - there's no type for domain property (in my case).
