Add support for Python 3.13

[tconbeer]

Looks like tree-sitter may have added 3.13 support, but now I get a numpy issue:

~ ❯ uvx --python 3.13 harlequin

This is the culprit:

i was wrong. There is still the textual/tree-sitter issue. Might need to update the textarea project to only use syntax highlighting in 3.12-, or implement our own syntax highlighting using a different tree sitter library.

Essentially blocked by:
Textualize/textual#4845

Hey Ted - I'm looking at this now from the Textual side. Can't promise anything but hopefully we'll be able to support 3.13 soon.

[darrenburns]

Support for syntax highlighting on Python 3.13 is in main in Textual now and should be released in the coming days.

Note that the new version of tree-sitter drops support for Python 3.8.

There's been a necessary few changes to the highlighting too which may affect Harlequin if you use the builtin SQL highlighting, so I recommend giving it a spin first. Let me know if there's any issues!

Thanks so much, @darrenburns !

This is out now in the latest Textual release.

When installing with uv tool install --python 3.13 harlequin, I had to move to use uv tool install --python 3.13 --with numpy harlequin.

It installed fine with the first command, but couldn't actually find numpy at runtime (with a similar ModuleNotFoundError: No module named 'numpy' error as this issue originally started with).

[tconbeer]

The latest commit on main supports 3.13; the latest release does not. Hoping to wrap one more breaking change into main and then release as 2.0. Maybe this week, we'll see.

Got it - thank you!
