Replace conda with mise+uv

[v4ld3r5]

Overview

This PR replaces the legacy Conda-based development setup with mise and uv, keeping the local environment isolated while simplifying the default Linux workflow.

It addresses #534.

Summary

• Migrated local development from the Conda environment files to mise and uv.
• Added .mise.toml to manage project-local Python and uv versions and the virtual environment.
• Added uv.lock for reproducible dependency resolution.
• Added explicit, mutually exclusive cpu and gpu extras for the PyTorch installation.
• Added a development dependency group for testing, linting, notebooks, and pre-commit.
• Removed the legacy Conda environment definitions and optional Conda test path.
• Fixed the calibration tests by preventing functools.partial callbacks from being bound as instance methods.
• Simplified GitHub Actions: Ubuntu uses mise's precompiled Python and no longer installs Python build dependencies; the workflow continues to resolve dependencies with uv and run linting/tests through uv run.
• Kept Python compilation as an explicit macOS-only installation step for the optional modules needed by NAM:
  • MISE_PYTHON_COMPILE=true mise install
• Updated the installation documentation with Ubuntu/Linux as the default path and the macOS exception.

Validation

• uv lock --check
• git diff --check
• Workflow YAML parsing
• Sphinx documentation build
• Tests passed locally
