init typing

[n-gao]

This PR adds typing support to seml. It also adds pyright to CI and pre-commit. For syncing the pre-commit dependencies we have a small script that will automatically pull the right dependencies from the pyproject.toml.

I changed a bunch of development and CI settings to cover Python and package versions better. I made the following changes:

• dropped support for Python 3.8, 3.9
• test in CI for the lowest and highest versions of each package
• I switched the CI completely to uv for faster CI times
• I also changed the instructions for seml development to use uv since that enables consistent, reproducible results with a lock file.

I also added very rudimentary support for non-conda environments by simply ignoring site-packages when uploading source files. Afaik, seml should just work fine without a conda environment since at the time of submitting a job, slurm will copy all environment variables anyway from the current shell. An issue arises if the virtual environment that submits the slurm job is not the same as the one is called add. I guess there are several options:

• Always copy all environment variables when adding an experiment and using these when submitting a job
• Supplying a path to the Python interpreter (this one could have unintended side effects as not all env vars might be set correctly, but I am not extremely deep into the pep about virtualenvs)
• Accepting conda environments or activate scripts from virtualenvs
