reflex-release@0.1.0a1

Features

• New package: reflex-release extracts Reflex's changelog-driven release pipeline — the towncrier news-fragment workflow, the changelog-as-source-of-truth publish detection, and the human-gated PyPI upload — into a reusable tool other repositories can adopt with uvx reflex-release init. It scaffolds the GitHub Actions workflows into the consuming repository (required for PyPI trusted publishing, which validates the workflow's own repository) and keeps them in step with reflex-release sync --check. Repository shape lives in a [tool.reflex-release] table: single package or monorepo, branch policy, lockstep groups that release together at one version, and internal packages that release without a changelog. Every upload waits on an approval from the pypi environment's required reviewers, and the artifacts it covers are named by SHA-256 in the run summary and in a manifest attached to the GitHub release. See packages/reflex-release/README.md for setup, configuration and the security model. (#6868)
