Jyotish Vedic Astrology — Comprehensive calculation engine

A Python package for Vedic (Jyotish) astrology calculations:
- D1-D60 divisional charts (Varga)
- Vimshottari Dasha (planetary periods)
- Shadbala (six-fold planetary strength)
- Ashtakavarga (eight-fold bindus)
- Yoga detection (planetary combinations)
- Nakshatra analysis
- Transit calculations
- Full-reading synthesis
