feat: Add augmentation management as the 8th unified method! 🧩

BREAKING CHANGE: Brainy 1.0 now has 8 unified methods (was 7)

Added complete augmentation management system:
- brain.register(augmentation) - Register custom augmentations
- brain.unregister(name) - Remove augmentations
- Existing enable/disable/list methods remain

CLI augmentation commands:
- brainy augment list - Show all augmentations
- brainy augment enable/disable - Toggle augmentations
- brainy augment register - Load custom augmentations
- brainy augment enable-type/disable-type - Bulk operations

Documentation:
- Created UNIFIED-API.md explaining all 8 methods
- Shows complete before/after transformation
- Includes augmentation pipeline architecture
- Examples for creating custom augmentations

The unified API is now complete:
1. add() - Smart data addition
2. search() - Unified search
3. import() - Bulk import
4. addNoun() - Typed entities
5. addVerb() - Relationships
6. update() - Smart updates
7. delete() - Soft delete
8. register() - Augmentations ⭐ NEW!

This completes the vision: ONE way to do everything!
