Adds `BetaToolRunner` which automatically handles the conversation loop between the assistant generating tool calls, executing those tool calls, and sending results back until a final answer is produced. Includes streaming support, concurrent tool execution, configurable iteration limits, and a `toolrunner` package with helper constructors for defining tools from JSON schema, map, or struct types.
