feat: v5.1.0 - VFS auto-initialization and complete API documentation

Browse source 
BREAKING CHANGES:
- VFS API changed from brain.vfs() (method) to brain.vfs (property)
- VFS now auto-initializes during brain.init() - no separate vfs.init() needed

Features:
- VFS auto-initialization with property access pattern
- Complete TypeAware COW support verification (all 20 methods)
- Comprehensive API documentation (docs/api/README.md)
- All 7 storage adapters verified with COW support

Bug Fixes:
- CLI now properly initializes brain before VFS operations
- Fixed infinite recursion in VFS initialization
- All VFS CLI commands updated to modern API

Documentation:
- Created comprehensive, verified API reference
- Consolidated documentation structure (deleted redundant quick starts)
- Updated all VFS docs to v5.1.0 patterns
- Fixed all internal documentation links

Verification:
- Memory Storage: 23/24 tests (95.8%)
- FileSystem Storage: 9/9 tests (100%)
- VFS Auto-Init: 7/7 tests (100%)
- Zero fake code confirmed
