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

|

* Returns a cached VFS instance that is auto-initialized during brain.init().
|

* No separate initialization needed!

*
|

* ```typescript
|

* await brain.import('./data.xlsx', { vfsPath: '/imports/data' })
|
||||
*
|
||||
* const vfs = brain.vfs()
|

* 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!
|

|
||||
* 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
