Project-scoped multi-environment workspace management for conda, with pixi compatibility
copied from cf-post-staging / conda-workspacesconda-workspaces brings project-scoped multi-environment workspaces and a task runner to conda as a plugin. Define environments, features, dependencies, and tasks in a single manifest (conda.toml, pixi.toml, or pyproject.toml) and let conda handle the solving and installation.
Optional dependencies for additional features: - conda-pypi: PyPI dependency resolution and installation - conda-rattler-solver: rattler solver backend (required for PyPI deps)
