[BUG] bash mode persists in queued messages

Preflight Checklist

What's Wrong?

lets say I run something in bash mode: ! ./run_tests. Then queue a message while this is happening: "> Plan a fix for the failing tests.".

Claude will finish running the tests and issue an error like:

! Plan: command not found.

What Should Happen?

The bash mode should not be sticky and the message should not be queued as a bash mode message. Also because I specifically wrote the message before a > without !.

Error Messages/Logs

Steps to Reproduce

1. run a long bash mode
2. queue normal message
3. See normal message failing because first work of message is not a valid bash command.

! sleep 10 && ls
  ⎿  CLAUDE.md
     filters
     LICENSE
     … +11 lines (ctrl+o to expand)

! Which folders did you find?
  ⎿  (eval):1: no matches found: find?

Note that when I wrote the "Which folders did you find?" it was before a >, not a !
