            Automated regen of the Buf-generated PHP archive.

            Schema commit `${{ steps.schema.outputs.commit }}` resolved from
            `buf.build/openstatus/api:main`.

            Source: ${{ steps.schema.outputs.source_control_url }}

            `scripts/regen.sh` fetches the archive from the `main` label and
            writes the resolved commit to `src/Gen/VERSION`. Trigger this
            workflow manually with a `commit` input to override the resolved
            value.
