Version 0.2.4

Performance & Scalability
- Blocklist content moved from chrome.storage to IndexedDB — removes storage size limits for large blocklists
- Extended blocking now uses in-memory domain Sets via webNavigation API, enabling support for blocklists far exceeding the 5,000 declarativeNetRequest rule limit
- declarativeNetRequest rules now properly capped at 4,900 to stay within browser limits

Filter / Blocklist Management
- New "Load" button for URL-based blocklists: preview line count and file size before adding, with cancel support for large downloads
- File upload now shows file name, line count and size after selection
- Deleting a blocklist now also removes its stored content from IndexedDB

Bug Fixes
- Fixed missing declarativeNetRequest rule that caused some blocks to be skipped
- Fixed stats display loops
- Error handling added for updateDynamicRules failures

Permissions
- Added webNavigation permission (required for extended blocklist matching)
