fix: propagate container.id across toolRunner iterations

[daletyler1737]

Summary

Fix two related bugs when using with :

1. Bug 1: is not automatically forwarded from one iteration to the next
2. Bug 2: The workaround using either fails immediately or causes infinite loop

Root Cause: When using , each response includes a that must be passed to subsequent requests. The current implementation doesn't extract and forward this .

Fix: After receiving a message response, extract the (if present) and store it in for use in subsequent message creations.

Code Change:

// Forward container.id from response to next request for code_execution_20250120
if (this.#message?.container?.id) {
  this.#state.params.container = {
    id: this.#message.container.id,
    skills: (this.#message.container as any).skills ?? undefined,
  };
}

Fixes #964
