Drop Python 3.8, 3.9 support to match napari and add precommit

[willingc]

This PR replaces #22. It does the following:

• add support for Python 3.13
• drop support for Python 3.8 and 3.9
• update templates to be consistent with these versions
• add pre-commit config file to the repo. Includes argument to ruff format single quote style to match napari's pyproject.toml config
• fix linting errors flagged by pre-commit
• exclude jinja files from the repo's pre-commit check for end-of-file fixes since it requires changes to the end-of-file for template jinja files. When an extra newline is placed on the jinja files, it causes the generated-from-template files to fail testing.

OH SHOOT, I guess with maintainer privileges I can directly push to this PR 😬 Lesson learned

Normally it prompts me to instead make a branch and commit to the branch, so hopefully this doesn't break anything. During my review I was noticing the double quote style and wanted to lint as if it were single like in napari/napari. I'll leave it run the tests. Sorry if I break it 💀

Ok I canceled it. The break is entirely on me. Maybe pre-commit can't trigger this arg?

[TimMonko]

@willingc Thank your for your persistence! I appreciate your explanation on the exclusion of the end-of-file linting for jinja files. Overall, the linting looks nice

I would like you to clarify for future maintainers: Did dropping 3.8/3.9 and adding 3.13 require these linting changes? If not, and we just changed python-versions, would the tests have been so troublesome?

One thing I noticed is that it uses double quote style. In napari/napari/pyproject.toml there is

[tool.ruff.format]
quote-style = "single"

I don't think that's a blocker at all for this PR, but could be nice to include? Might be done with in precommit but I'm not sure yet

- repo: https://github.com/astral-sh/ruff-pre-commit
  rev: v0.9.9
  hooks:
  - id: ruff-format
    exclude: examples
    args:
      - "--quote-style=single"
  - id: ruff

[TimMonko]

I can't figure out how to properly pass the quote-style single in pre-commit, so I think I'll let the tests run and merge?

I'm glad you are such an encouraging person and totally don't mind me figuring this all out in the fire so-to-speak

@TimMonko I think the proper syntax is:
args: [--config, format.quote-style = 'single']
based on astral-sh/ruff#9743

[willingc]

Good questions. The changing of the python versions was not the issue. It was adding pre-commit to the repo and having it fix the existing files (which broke the template files end of file behavior).

No worries on applying any changes. I can easily rebase to remove if needed though tests are passing. Feel free to iterate on it more. I'm at a conference today so will be slow to respond.

[willingc]

Oh and please feel free to switch to single quotes as you prefer. I pulled the .precommit.config.yaml from the napari repo itself.

[willingc]

@TimMonko Single quotes look good. Tests are passing. You can press the green button (just use the defaults when it pops up the next screen.

@psobolewskiPhD great work sleuthing how to do that! I read that like 8 times earlier and definitely did not pick up how to format the arg correctly.

@willingc again, great great work! I'll update PR description to explain the single quote addition.
