Auto Tab Group

# Auto Tab Group

Auto Tab Group automatically organizes your browser tabs into Chrome Tab Groups using simple hostname/URL patterns.

## Key Features
- Auto grouping: groups tabs that match your configured patterns.
- Strict groups: optionally remove tabs from a group when their URL no longer matches the group's patterns.
- Minimum threshold: require a minimum number of matching tabs before creating a group (configurable per group).
- Per-group enable/disable: quickly toggle individual group rules from the popup list.
- Global enable/paused toggle: pause all automatic grouping from the popup badge.
- Persistent settings: rules are stored in `chrome.storage.sync` so they follow your browser profile.
- Respects pinned tabs and works across all windows.
- Reuses existing Chrome groups when titles match; updates group title and color.
- Debounced grouping to avoid rapid re-grouping (500ms debounce).
