[BUG] messages queued instead of sent even if claude is not busy

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

queued messages sometimes won't be sent and will just sit in the queue, requiring a restart of claude code

When this happens, any message sent becomes queued and is not actually sent through.

What Should Happen?

queued messages should always be sent whenever Claude has finished the previous task.
