* Changed:
* Updated Dunamai to 1.23.0+ for the latest features.

* Fixed:
* There was an intermittent `ValueError` in PEP 621 mode,
related to trying to remove `"version"` from `project.dynamic`
when it had already been removed.

* Added:
* The `enable` command now supports the bypass/override environment variables
to use a different placeholder version than 0.0.0.
* Fixed:
* The `enable` command would add `"version"` to `project.dynamic` even if it were already present.

* The `enable` command would set `tool.poetry.version` to `"0.0.0"`
even if the field were already present with a different value.

* Added:
* CLI: `show` command to print the version without changing any files.
