Bump version to v0.7.1

Release v0.7.1 with native precision support and architectural improvements:
- Native float32/float64 precision throughout the entire stack
- Eliminated idx2exact complexity for simpler code
- Auto-detection for precision based on dtype and file loading
- Advanced precision control (adaptive epsilon, configurable epsilon)
- Fixed precision validation gaps and query precision issues

Changes:
- pyproject.toml: 0.7.0 → 0.7.1
- __init__.py: 0.7.0 → 0.7.1
- CHANGES.md: Updated release date to 2025-11-09
