Summary

Bump version in pyproject.toml from 0.2.6 to 0.2.7 to match the v0.2.7 tag.

Context

The publish workflow triggered on tag v0.2.7 but pyproject.toml still had version = "0.2.6". PyPI rejected the upload because 0.2.6 already exists.

After merging, delete the existing v0.2.7 tag and re-tag from the updated main:

git tag -d v0.2.7
git push origin :refs/tags/v0.2.7
git tag v0.2.7
git push origin v0.2.7
