Amazon Q CLI shell integration interferes with Home key + "#" comment workflow

### 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

### Operating system

Linux 6.14.6-200.fc41.x86_64 - Fedora Linux 41 (Workstation Edition)

### Expected behaviour

When pressing Home key to move cursor to beginning of line, then typing "#" to comment out a command, the command should be treated as a comment and added to history without execution.

### Actual behaviour

pressing home key to move cursor to beginning of line, then typing "#" to comment our the command results in

`q translate ''`

for example, this is how it becomes in terminal when i tried to comment out the vi command

```
q translate 'vi ~/.local/share/amazon-q/shell/bashrc.post.bash'vi ~/.local/share/amazon-q/shell/bashrc.post.bash
```

### Steps to reproduce

1. Install Amazon Q CLI
2. Type a command in terminal but don't press Enter
3. Press Home key to move cursor to beginning of line
4. Type "#" to comment out the command
5. Press Enter
6. Observe that instead of being treated as a comment, the command is interpreted as "q translate "

Riproduci questo nell’integrazione shell di Amazon Q CLI su Fedora Linux digitando un comando, premendo Home e quindi digitando #. Ispeziona amazon-q/shell/bashrc.post.bash e il comportamento dell’integrazione shell circostante; il lavoro è completato quando la riga rimane un commento, viene aggiunta alla cronologia e non invoca q translate.
