Release v0.2.1

Fixed

• When a member removes their cast.json, their directory card falls back to GitHub data instead of keeping the old title and tagline (#12)
• A merged pull request total that was not fetched from GitHub is labelled self-reported, never live (#12)
• Taglines with accent markup show as text on directory cards and in the terminal, without literal asterisks (#12)
• Stat numbers keep their suffix on the same line, GitHub-only intros read as sentences, the search field shows a focus ring, and the 404 heading fits on small screens (#12)
• Verification badges show the since date as month and year, matching the directory cards (#12)
