chore: Set up CI for copick-utils

[uermel]

This PR sets up CI for copick-utils.

Details:

Switch build system

Switches from poetry to uv for the build system. Use hatchling-vcs for dynamic versioning.

Set up pre-commit / linting action

Introduces new extra dev, which installs necessary build system packages and black and ruff linters. Linting rules can be enforced using pre-commit:

uv pip install -e ".[dev]"
pre-commit install
pre-commit run --all-files

Also sets up a github action that enforces the linting rules before merging PRs.

Set up release-please and conventional-commits

Sets up release-please action for automated generation of release PRs based on conventional commits naming conventions. Hereafter, PR titles will have to use conventional commits prefixes.

• The variable 'radius' is not defined in this function. Consider passing 'radius' as a parameter or using the correct existing variable to compute grid_spacing.

    grid_spacing = radius * grid_spacing_factor

src/copick_utils/segmentation/picks_from_segmentation.py:5

• The 'watershed' import is not used in this module. Remove it or use it in place of current segmentation logic to keep the imports clean.

from skimage.segmentation import watershed
