* mount: tell windows about changes made elsewhere Nothing invalidates a Windows client's cache from this side, so a file created or removed by another mount, the S3 gateway or the filer API stayed invisible in Explorer until the user refreshed by hand. The mount already receives those events; they just had nowhere to go. WFS gains a listener for every applied metadata event, and on Windows that turns into the WinFsp notification for the path. A rename reports both ends, since the destination's own event may never arrive when it falls outside this mount. * mount: report a removed directory as a directory Entry is nil once a path is vacated, so asking it whether the thing that went away was a directory always answered no and every removal was reported as a file. Windows watches the two through different filters, so a folder removed elsewhere never refreshed. The invalidation now carries what used to be there, which the event already knew and simply was not passing on. * mount: report a rename destination once The event stream already carries a second invalidation describing the new path, so reporting RenamedTo here sent the destination twice — and always as a create, so a moved directory arrived as a create followed by a mkdir.
