Goal 2: Package Identity #238

Experience: Users install one package, mlc-chakra, and always get the current main code.

Acceptance criteria

• pyproject.toml names the distribution mlc-chakra. Evidence: PR link.
• The version comes from the git tag and is never edited by hand. Evidence: PR link, plus the Version: line from a built wheel's metadata.
• A wheel built at tag vX.Y.Z is named mlc_chakra-X.Y.Z-py3-none-any.whl, and import chakra works from it in a clean environment. Evidence: CI log.

Dependencies: Goal 1, which merges #225 and #233 (the rename rebases on both) and #195's pin (it also edits [build-system]).

Current decisions

• Distribution name mlc-chakra
• The version comes from the git tag (Proper versioning #232)
• Transfer Changes needed for pypi packaging #214 changes to a new PR fix comments then merge
