Q CLI sometimes likes to repeat itself twice or thrice, doing git commands like commit multiple times, adding a pipe to head that doesn't appear to add any value

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue
- [x] I have run `q doctor` in the affected terminal session
- [x] I have run `q restart` and replicated the issue again

### Operating system

macOS 15.4.1 (24E263)

### Expected behaviour

That when Q CLI decides to commit a change or grep, or other commandline, it won't do it more than once unless it somehow expects different results which it should explain in the Purpose.

### Actual behaviour

Snippet, with internal references redacted.

### Steps to reproduce

Not sure exactly what it takes to reproduce. It seems to appear more often in longer running Q sessions.
