fix(llm): correct boolean parameter type to 'boolean'

The enum value for `ToolParamType.BOOLEAN` is updated from 'bool' to 'boolean'. This change aligns the type definition with the standard JSON Schema specification, which is used by most LLM tool-calling APIs. This ensures correct validation and functionality for tools with boolean parameters.

BREAKING CHANGE: The value of `ToolParamType.BOOLEAN` has been changed from 'bool' to 'boolean'. Any part of the system that generates or consumes tool definitions must be updated to use the new value.
