Command ergonomics need help

[jaraco]

Currently, the only way to build or test a coherent system project is to run python -m coherent.{module}, and since pipx doesn't provide an easy way to do that, the best model is pip-run, e.g.:

pip-run coherent.build -- -m coherent.build

That's not beautiful. I'd really rather there be a single installable command for coherent build or coherent test.

With the release of coherent.cli 0.1, it's now possible to run simply coh build or coh test.
