feat: add TarotCard component with 78-card deck support

[gfargo]

Summary

Adds a new TarotCard component built on top of the existing CustomCard API, along with a createTarotDeck() utility for generating a standard 78-card tarot deck.

What's included

TarotCard component (src/components/TarotCard/)

• Wraps CustomCard with tarot-specific semantics via a discriminated union on arcana
• Major Arcana (arcana="major" + majorIndex 0–21): ASCII art for all 22 cards, roman numeral corner symbols, yellow/magenta theming
• Minor Arcana (arcana="minor" + suit + value): Auto-generated pip art for numbered cards, court card rendering, cyan theming
• Tarot suits: wands (🜂), cups (☽), swords (⚔), pentacles (⛤)
• reversed prop for upside-down card readings
• Custom tarot-themed card back with celestial pattern
• All BaseCardProps pass through (faceUp, selected, rounded, effects)

createTarotDeck utility (src/components/TarotCard/utils.ts)

• Produces a standard 78-card tarot deck:
  • 22 Major Arcana (The Fool through The World)
  • 56 Minor Arcana (Ace–10 + Page/Knight/Queen/King × 4 suits)
• Unique IDs for every card

Tests (TarotCard.test.tsx)

• 22 tests total: 16 snapshot render tests + 6 createTarotDeck validation tests
• Covers Major/Minor Arcana, reversed, face-down, selected, custom colors/art
• Deck tests verify: 78 total cards, 22 Major, 56 Minor, 14 per suit, unique IDs, correct indices

Storybook (TarotCardView.tsx)

• Added to storybook menu with ☾ indicator
• Demos: Major Arcana (paginated), Minor pips, court cards, reversed cards, all four suits
• Face up/down toggle

Usage

// Major Arcana
<TarotCard id="fool" arcana="major" majorIndex={0} />

// Minor Arcana (reversed)
<TarotCard id="qc" arcana="minor" suit="cups" value="Queen" reversed />

// Full 78-card deck
const deck = createTarotDeck()

Checklist

• Builds cleanly (yarn build)
• All 217 tests pass (yarn test:fix)
• Exported from public API (src/index.tsx)
• Storybook integration
• Standard 78-card deck (22 Major + 56 Minor)
