uv and pyproject.toml

[shamrin]

Migrate to uv and pyproject.toml.

To upgrade local development environment, install uv and run:

# clean up old environment
rm -rf datacrunch.egg-info/ .venv/ datacrunch_env/

# initialize new environment and install dependencies
uv sync

# run examples
uv run python examples/simple_create_instance.py

Virtual environment changes:

1. No need to to activate venv in the shell, simply prefix commands with uv run. But, if you must, activating is still possible.
2. To select virtual environment in VSCode:Python: Select Intepreter -> ./.venv/bin/python

See changelog for more details.

It's not used (pointed out by Ruff linter).

[shamrin]

Fixes a deprecation warning.

[shamrin]

Module removed to prevent confusion with commonly expected: from datacrunch import __version__; print(__version__).

See next PR #50
