ci(release): verify wheels and reuse quality checks

[nichinichisou0609]

Release builds now run the existing Python, golden-record, and Rust checks before the distributions can be published. Each platform also installs its freshly built wheel into a temporary environment and checks the command-line entry point and extension with a synthetic deck-data document.

The CI workflow is reusable, with concurrency scoped to its caller so ordinary CI and release checks can run independently.

Validation:

• actionlint passed for both workflows.
• PR CI passed on Python 3.11–3.14, including the separate strict golden-record and Rust checks.
• Release preflight passed, including all five installed-wheel smoke checks and distribution validation. The PyPI and GitHub publication jobs were skipped for the manual run.
