v0.7.23

Fixed — found by installing from PyPI and using it as a newcomer

• epochix --version failed. It was handed to run, which answered "No
  such option: --version" under a "Usage: epochix run" banner. It prints the
  version now (-V too).
• Giving epochix a folder instead of a log file crashed with a Python
  traceback (a PermissionError on Windows) and left a run stuck "in
  progress" in epochix list for good. It is refused up front, with a
  one-line message, before anything is stored; the same goes for --tail and
  the SDK's parse(), which raises IsADirectoryError.
• epochix doctor could report the wrong version — that of an older copy
  installed beside the one running. It reports the running one.
• The CLI reference left out three commands: doctor,
  import-tensorboard and import-wandb. They are documented, with
  --version, and a test now fails if a command is missing from it.
