Fixed
- A build from the source distribution runs on what that distribution carries. 2.29.0 named toml-fmt-common as a dependency and resolved it from PyPI, where the newest release dates from May; 2.29.1 dropped the dependency before the sdist carried the sources, so a build from it failed on the import. This release carries them, and its metadata requires nothing. (#450, #452)
The wheels held their vendored copy throughout, so an install that takes a wheel was never affected.
