Add VTS PersonToken integration and age-restricted spending
- Require Vita (soul-bound identity token) for minting restricted VTS - Add age-restricted vendor flag for age-gated purchases (e.g., alcohol) - Add IsAdultVerified method to PersonToken for age verification - Update spend/canSpendAt to check age verification for restricted vendors - Add toBool helper function for boolean stackitem parsing - Add comprehensive tests for age-restricted functionality 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
