Feature: Stop button interrupts active turn without missing turnId

Prerequisites

• App is running from this repository.
• At least one thread can run a long response (for example, request a large code explanation).

Steps

1. Send a prompt that keeps the assistant generating for several seconds.
2. Immediately click the Stop button before the first assistant chunk fully completes.
3. Confirm generation halts.
4. Repeat with a resumed/existing in-progress thread (reload app while a turn is running, then click Stop).

Expected Results

• No error appears saying turn/interrupt requires turnId.
• Turn is interrupted successfully in both immediate-stop and resumed-thread scenarios.
• Thread state exits in-progress and the stop control returns to idle.

Rollback/Cleanup

• None.
