Automate release publishing via GitHub Actions (#493)

* Automate release publishing via GitHub Actions

Add a release workflow triggered on tag push that publishes to Maven
Central, Gradle Plugin Portal, and creates a GitHub Release. Simplify
CI snapshot publishing to use a single vanniktech publishToMavenCentral
task and pass secrets via env vars instead of -P flags.
