feat: add card generator
Adds /generators/cards/ — draws 1–52 cards from a standard 52-card deck. Supports unique draws (Fisher-Yates) and with-replacement mode. Cards rendered as mini playing-card tiles with red suits coloured. Clipboard copy in rank+suit format (e.g. A♠, K♥). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
