Experiment with uv

[colindean]

uv is fast rising in popularity. It's written by Astral, the same folks behind ruff.

It does everything that Poetry does when combined with pyenv for Python installation, although its Python or even pyenv's may not be suitable for production use.

This experimentation should try swapping out poetry + pyenv in the Makefile to see what changes would be necessary.

I would not consider a wholesale switch until uv is 1.0.0, at which time I'd consider it with the values of

• first-time setup performance

• package installation performance (cold cache)

• package update performance (hot cache)

• availability of tooling replacements, e.g. diff-poetry-lockfile in our GitHub workflows

  make-python-devex/.github/workflows/make-based-ci.yml

  Lines 22 to 24 in 669a039

  	# This will post a comment on PRs when poetry.lock changes
  	- name: Diff poetry.lock
  	uses: nborrmann/diff-poetry-lock@c0afd3666864cec339f03ee5c5cf9cb671780c12

• minimization of helper tasks e.g. poetry-venv-implode.

  make-python-devex/Makefile

  Lines 314 to 316 in 669a039

  	.PHONY: poetry-implode-venv
  	poetry-implode-venv: ## Destroys the Poetry-managed virtualenv
  	sleep 2 && rm -rf $$($(POETRY) env info --path)

• lockfile improvements (e.g. standardization track vs bespoke, diff-able, etc.)

• others TBD
