bug: q uninstall fails when Amazon Q.app is installed in user Applications folder (~/Applications)

### 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 15.1.1

### Expected behaviour

## Description
When Amazon Q.app is installed in the user's Applications folder (`~/Applications`), the uninstall command fails with the error:
```
error: Invalid input method bundle: Could not load bundle for URL /Applications/Amazon Q.app/Contents/Helpers/CodeWhispererInputMethod.app
```

The command is looking for the app in the system-wide `/Applications` folder instead of the user's `~/Applications` folder where it's actually installed.

## Expected behaviour
The `q uninstall` command should successfully uninstall `Amazon Q.app` regardless of whether it's installed in the system-wide `/Applications` folder or the user's `~/Applications folder`.

Note: it is [documented by Apple][1] that `~/Applications` contains "user-specific apps".

### Actual behaviour

The `q uninstall` command fails with the error:
```
error: Invalid input method bundle: Could not load bundle for URL /Applications/Amazon Q.app/Contents/Helpers/CodeWhispererInputMethod.app
```

### Steps to reproduce

1. Install Amazon Q.app in the user's Applications folder (~/Applications) by mounting the installation image (`dmg`), then manually copying `Amazon Q.app` from the mounted image into `~/Applications` (create the folder if it doesn't exist)
2. Run `q uninstall` in the terminal
3. Observe the error message about not being able to load the bundle from /Applications/Amazon Q.app (wrong path)
