Amazon Q terminal integrations: qterm is not running in this terminal, please try restarting your terminal

### 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

Linux 6.8.0-136-generic - Ubuntu 22.04.5 LTS

### Expected behaviour

It's simple, can use Amazon Q CLI 1.19.7 without fail as I already using Amazon Q CLI 1.15.0. I want to use Amazon Q CLI (Not Kiro).

### Actual behaviour

I'm facing to use q, echo `Q_TERM`, see the output below:

```
echo "Q_TERM=$Q_TERM"
q doctor
Q_TERM=

✘ Amazon Q terminal integrations: qterm is not running in this terminal, please try restarting your terminal

Q_TERM=

✘ Doctor found errors. Please fix them and try again.

If you are not sure how to fix it, please open an issue with q issue to let us know!

```

### Steps to reproduce

**1. Download Amazon Q CLI**
```
cd ~/Downloads

curl --proto '=https' --tlsv1.2 -sSf \
https://desktop-release.q.us-east-1.amazonaws.com/latest/q-x86_64-linux.zip \
-o q-x86_64-linux.zip
```

**Verify:**

`ls -lh q-x86_64-linux.zip`
**2. Extract**
```
unzip -o q-x86_64-linux.zip
```
**Install correctly**
**Run:**

```
cd ~/Downloads/q
chmod +x install.sh
./install.sh
```

If it asks to modify your shell configuration, choose **Yes**.

**Then reload Bash:**

```
source ~/.bashrc
hash -r

```
**Verify**
```
which q
q --version
```

**Then verify the chat binary:**

```
which qchat
qchat --version
```

**Also:**

`q doctor`

I tried all the possible fixes along with `q integrations reinstall dotfiles` and nothing is helped me..

Thanks in advance..!

Start by reproducing the empty Q_TERM result with q doctor in the documented Ubuntu 22.04 Bash and GNOME Terminal setup. Read the q restart and q integrations reinstall dotfiles entry points, then compare the installed q 1.19.7 behavior with the reported qterm integration state. Done means the terminal integration initializes and q doctor no longer reports that qterm is not running.
