feat: comprehensive metadata namespace architecture and cleanup system
BREAKING CHANGE: Remove hard delete option from deleteVerb() for consistent API - Add complete metadata namespace architecture with O(1) soft delete performance - Implement periodic cleanup system for old soft-deleted items - Add restore methods for both nouns and verbs - Require metadata contracts for all augmentations - Eliminate namespace collisions with clean separation (_brainy, _augmentations, _audit) - Optimize index performance using flattened dot-notation for O(1) lookups - Add comprehensive augmentation safety system with type-safe access control - Maintain full backward compatibility for existing data - Add enterprise-grade cleanup with configurable age thresholds and batch processing 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
