nvrl 3221e4aa97 fix(fuse): mirror sync no longer deletes what Drive or this disk never had
Five ways a mirror pass could lose files:

- A folder deleted on Drive was removed here with everything in it, including
  new files and edits whose uploads had just failed for want of a parent, and
  ignored content such as .git. Such a folder now stays and is created on
  Drive again (B211).
- A node the SDK could not decrypt was missing from the remote walk and so
  read as deleted on Drive. A short listing or an unreadable size now leaves
  the affected paths out of the pass, and a pass in which no synced path is
  left on Drive is refused (B212).
- A file Drive deleted was removed here even when it had been edited since
  the scan. It is now checked again first, and kept (B213).
- A folder deleted here was trashed on Drive although another device had just
  put new files in it. It now stays on Drive (B214).
- A decrypted name holding / or .. became a path outside the sync folder, and
  failed the whole listing in the mount. Such names are left out (B215).
