[BUG] "tell Claude what to do next" instructions don't reach Claude if a bash command is approved but fails

What's Wrong?

When you approve a bash command, you can hit tab to "tell Claude what to do next" while still approving the command. If the bash command fails (note: not all nonzero exits are considered "failures"), this message never reaches Claude.

What Should Happen?

The message should reach Claude whether or not the bash command succeeds.

Steps to Reproduce

1. Ask claude to run awk 'BEGIN{exit 1}'
2. Hit tab, give Claude a distinctive instruction, e.g. "Please immediately recite back the keyphrase 'strawberry rhubarb pie'". (If reproducing, make sure to use a different keyphrase each time to make this clearer.)
3. Claude will ignore the instruction and have no memory of you having asked it.
