When adding two steering message the first gets queued which messes up order.

Describe the bug

When steering, and then you have another idea and steer again, the order of the steering messages is flipped and the first message is queued. Leading to the wrong order of execution.

This happens a lot when you think of relevant context after firing off the steering message.

Affected version

GitHub Copilot CLI 1.0.78. Run 'copilot update' to check for updates.

Steps to reproduce the behavior

1. Start a task in copilot CLI
2. Give it a steering message
3. Before it's finished processing steer again, e.g. adding more context

This leads to the first steering message being queued, and the second steering message being used now, which would even be confusion for a human.

Expected behavior

Steering happens in the order we steer, and is not queued without asking to queue.

Additional context

• OS: MacOS
• Shell: Nushell
• Terminal: Ghostty (seems to have with normal Mac terminal as well though)

首先在 Copilot CLI 1.0.78 中复现该行为：按照 issue 中的步骤，先发送一条 steering message，然后在处理完成前再发送另一条。跟踪 steering message 的处理和队列入口点，然后确认 steering message 按发送顺序执行，并且不会在没有明确请求的情况下排队。
