What's new in 0.3.0

• Rich per-site view: click any site in the dashboard for stat tiles, a 30-day chart, a GitHub-style activity heatmap, and day-of-week averages.
• In-page limit warnings: a banner at 80% of a site's daily limit and a "Time's up" overlay at 100%, shown on the site itself. System notifications remain as a fallback when the site isn't open.
• Pin sites with a bookmark ribbon to keep them at the top of the list.
• History is now kept for 365 days (up from 90). Beyond the top 200 sites, time folds into an "everything else" bucket so totals stay honest.
• Set or change a site's limit right from its detail view.
