Don't Close Last Tab από Prayōgaśāla

Prevents accidental window closure by automatically opening a new tab when you close the last tab. This extension adds a pinned guard tab that appears when you have only one tab remaining, ensuring your window stays open even if you close that last tab.

Features:
- Automatically creates a new tab when the last tab is closed
- Uses a pinned guard tab that's unobtrusive
- Works with multiple windows independently
- Minimal permissions required (tabs only)
