feat: add new stats entry for March 2026 and update stats calculation logic

- Added a new stats entry for March 12, 2026, including total posts, downloads, views, upvotes, saves, followers, points, contributions, and detailed post statistics.
- Updated the stats calculation logic in `openwebui_stats.py` to only count views for posts with actual downloads, excluding post and review types.
- Introduced a new script `zed-ai-tabs.sh` for batch-launching and orchestrating multiple AI CLI tools as tabs, including a single-instance lock mechanism and automatic tool discovery.
