Single workflow file at .github/workflows/release.yml that triggers
on v* tag pushes, assembles projects-portfolio-v<version>.zip from
an allowlist of runtime files, uploads as a workflow artifact, and
attaches to a matching GitHub release.
Adds a provider interface with GitHub and Gitea adapters so each
project can link to either provider. Preserves existing GitHub
behavior bit-for-bit, adds lazy migration from legacy meta, and
ships WP PHPUnit tests.
