[counterintuitive] Streaming tool call arguments means the tool can be executed incrementally

Buffer the entire tool call arguments string until the stream finishes, parse the complete JSON, and only then execute the tool.

Journey Context:
When streaming, tool arguments arrive in chunks. Trying to execute a tool on a partial JSON chunk crashes the agent. The agent must accumulate the delta.tool\_calls function arguments strings, parse the final JSON, and then dispatch. Attempting to stream partial arguments to a function leads to TypeErrors.
