* filer.remote.sync: resolve same-second updates with the sync stamp shouldSendToRemote compared remote_mtime to the entry mtime in whole seconds, so a rewrite landing in the same second as the previous upload was dropped and never retried. When the two seconds are equal, fall back to the full-precision LastLocalSyncTsNs stamp, the same check remote.uncache uses to refuse uncaching an unsynced entry. An entry without the stamp is treated as unsynced and sent. Fixes #11713 * filer.remote.sync: restamp the entry after a metadata-only remote update A same-second metadata edit now reaches UpdateFileMetadata, but without advancing LastLocalSyncTsNs the entry stays dirty and every later event re-sends the metadata update. Stamping it through updateLocalEntry keeps the same IF_ENTRY_EQUAL guard as an upload stamp. * filer.remote.sync: stamp a cloned RemoteEntry in updateLocalEntry Callers can pass the event's own RemoteEntry; mutating its stamp before the expected entry is cloned put the new stamp into IF_ENTRY_EQUAL while the filer still holds the old one, so every restamp was rejected as stale. Stamping a clone keeps the precondition on the stored stamp and leaves the caller's RemoteEntry untouched.
