Fix release workflow to publish to Maven Central via the Portal API

[jeremyprime]

Summary

The release workflow deployed to the OSSRH staging API with -DautoReleaseAfterClose=true, but that flag no longer works with the Portal compatibility API. It closed the staging repo but never releases it. The 2.0.0 deployment got stuck in VALIDATED and had to be published manually.

This switches publishing to the Central Portal Publisher API directly, mirroring the process used to publish 1.0.0.

Changes

• Build and GPG-sign the publishable modules locally (no staging deploy)
• Assemble a signed bundle (POM + jars + sources + javadoc + .asc + checksums)
• Upload to /api/v1/publisher/upload?publishingType=AUTOMATIC, then poll to PUBLISHED
• Remove the staging-repo cleanup step (no staging repo in this flow and the Portal docs also advise against dropping FAILED deployments)

Testing

Mostly followed a set of manual scripts that were used to release 1.0.0. Some of the steps were test manually locally during the 2.0.0 release, but others will need to be verified on the next release.

📝 Walkthrough

Walkthrough

The release workflow now builds and signs publishable modules locally, assembles a Maven Central bundle, uploads it through the Central publisher API, and monitors deployment status until publication succeeds or fails.

Changes

Maven Central publishing

Layer / File(s)	Summary
Build and sign release artifacts .github/workflows/release.yml	The workflow builds both publishable modules locally with Maven and creates signed artifacts without staging deployment.
Assemble the Central bundle .github/workflows/release.yml	The workflow creates the Central directory layout, adds POMs, jars, signatures, and checksums, and packages them as bundle.zip.
Upload and monitor deployment .github/workflows/release.yml	The workflow uploads bundle.zip with publishingType=AUTOMATIC, validates the deployment ID, and polls Central until PUBLISHED, FAILED, or a timeout condition occurs.

Merge Risk: 🟡 Moderate · up to d7ea9

The Maven Central publishing workflow can be cancelled during a normal longer deployment because its total job timeout is too short for artifact preparation and the configured publication polling period. Increase the timeout before merging to avoid failed or indeterminate releases.
