Matteo Collina 569369f927 vfs: dispatch fs/promises to mounted VFS instances
Add mount/unmount lifecycle on `VirtualFileSystem`, a handler registry
that fs.js and fs/promises.js consult via `vfsState.handlers`, and a
router that maps absolute paths to the VFS that owns them. When a VFS
is mounted, the public `fs.*` and `fs/promises` APIs (including
streams, `fs.watch`, and `opendir`) dispatch to the provider for paths
under the mount point, and fall through to the real filesystem
otherwise. Includes per-method dispatch tests, error-path coverage,
multi-mount routing tests, and router unit tests.
