v4.6.1

• Cache archives carry the whole generated tree. Collecting a generates
  glob for the cache now includes hidden entries — node_modules/.bin and
  every other dot file or directory under **/* — and stores a symlink to a
  directory as the link instead of following it into its target, so a restored
  node_modules runs and a Yarn workspace keeps its links. Fingerprint
  checksums still see what the shell lists, so .task state is unaffected.
• Failed cache imports invalidate saved task status. After an import
  fails, tasks rebuild instead of trusting partially restored outputs. If
  saved status cannot be removed, Task reports that cleanup failure too.
