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

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

* Virtual File System API - Knowledge Operating System
* Virtual File System API - Knowledge Operating System (v5.0.1+)
*
* Returns a cached VFS instance. You must call vfs.init() before use:
* Returns a cached VFS instance that is auto-initialized during brain.init().
* No separate initialization needed!
*
* @example After import
* ```typescript
* await brain.import('./data.xlsx', { vfsPath: '/imports/data' })
*
* const vfs = brain.vfs()
* await vfs.init() // Required! (safe to call multiple times)
* const files = await vfs.readdir('/imports/data')
* // VFS ready immediately - no init() call needed!
* const files = await brain.vfs.readdir('/imports/data')
* ```
*
* @example Direct VFS usage
* ```typescript
* const vfs = brain.vfs()
* await vfs.init() // Always required before first use
* await vfs.writeFile('/docs/readme.md', 'Hello World')
* const content = await vfs.readFile('/docs/readme.md')
* await brain.init() // VFS auto-initialized here!
* await brain.vfs.writeFile('/docs/readme.md', 'Hello World')
* const content = await brain.vfs.readFile('/docs/readme.md')
* ```
*
* **Note:** brain.import() automatically initializes the VFS, so after
* an import you can call vfs.init() again (it's idempotent) and immediately
* query the imported files.
* @example With fork (COW isolation)
* ```typescript
* await brain.init()
* await brain.vfs.writeFile('/config.json', '{"v": 1}')
*
* **Pattern:** The VFS instance is cached, so multiple calls to brain.vfs()
* const fork = await brain.fork('experiment')
* // Fork inherits parent's files
* const config = await fork.vfs.readFile('/config.json')
* // Fork modifications are isolated
* await fork.vfs.writeFile('/test.txt', 'Fork only')
* ```
*
* **Pattern:** The VFS instance is cached, so multiple calls to brain.vfs
* return the same instance. This ensures import and user code share state.
*
* @since v5.0.1 - Auto-initialization during brain.init()
