fix(vscode-ide-companion): resolve all ESLint errors

Fixed unused variable errors in SessionMessageHandler.ts:
- Commented out unused conversation and messages variables

Also includes previous commits:
1. feat(vscode-ide-companion): add upgrade button to CLI version warning
2. fix(vscode-ide-companion): resolve ESLint errors in InputForm component

When the Qwen Code CLI version is below the minimum required version,
the warning message now includes an "Upgrade Now" button that opens
a terminal and runs the npm install command to upgrade the CLI.

Added tests to verify the functionality works correctly.
