Update examples in descriptive property to use boolean type

[anson-usafacts]

Describe the bug
In mcp-server/src/schema/table.schema.ts, the descriptive property is defined to expect a boolean type, but the provided examples use strings:

 descriptive: {
    type: 'boolean',   <-- expect boolean
    description: 'Add variable labels to the second row of the API results.',
    examples: ['true', 'false'],    <-- examples are strings
  },

This causes an invalid_type error when the strings 'true' or 'false' are passed to the MCP (fetch-aggregate-data):

# Arguments:
{
  "dataset": "acs/acs1/profile",
  "year": 2023,
  "get": {
    "variables": [
      "DP05_0001E"
    ]
  },
  "for": "state:06",
  "descriptive": 'true'
}

mcp.shared.exceptions.McpError: MCP error -32602: Invalid arguments: [
  {
    "code": "invalid_type",
    "expected": "boolean",
    "received": "string",
    "path": [
      "descriptive"
    ],
    "message": "Expected boolean, received string"
  }
]

Model Details

• Model: gpt-5-mini
• Where the Conversation Occured: local development using the MCP (python)

Fix
This issue was fixed simply by updating the examples to be true boolean values ([true, false])

 descriptive: {
    type: 'boolean',
    description: 'Add variable labels to the second row of the API results.',
    examples: [true, false],    <-- use boolean types in examples
  },
