File paths with spaces need proper quoting

[konard]

🐛 Bug Description

File paths containing spaces fail to be properly quoted when interpolated through command-stream, causing commands to interpret them as multiple arguments.

🔴 Impact

• Operations on files with spaces in names fail
• Common on Windows/Mac with default folders like "Program Files"
• Affects file operations, directory navigation, and path handling

📝 Problem Example

```javascript
const filePath = "/Users/john/My Documents/report.txt";
// ❌ Fails - interpreted as multiple arguments
await $`cat ${filePath}`;
// Shell sees: cat /Users/john/My Documents/report.txt
// Interprets as: cat /Users/john/My + Documents/report.txt
```

🔧 Workaround

Manually quote the path:
```javascript
await $`cat "${filePath}"`;
```
