refactor(fs): reduce overhead of watch

[Legend-Master]

This PR changes a few things

• Migrate the watcher in js side to use Resource
• Remove WatcherResource and unwatch as they're not needed, notify's watcher will clean itself up on drop
• Remove the new thread and channel redirect on every watch, as they're not really needed

Also:

• Removed close command as it's not used anymore
• Updated metadata to stat in readme
• Removed uuid as dependency since it's not used anymore
