feat: Implement Tarot session management and reading spreads

- Added TarotSessionManager class to manage tarot reading sessions, including session creation, retrieval, reading addition, and cleanup of old sessions.
- Defined various tarot spreads in a new spreads module, including single card, three card, Celtic cross, and more, with detailed descriptions and meanings for each position.
- Created core types for tarot cards, readings, and sessions in a new types module to structure data effectively.
- Configured TypeScript settings in tsconfig.json for improved development experience and compatibility.
