Migrate to com.vanniktech.maven.publish plugin for Maven Central Portal

[Copilot]

Modernize Maven publishing configuration to support the new Maven Central Portal, following the approach from https://github.com/aizuda/flowlong.

Changes

build.gradle.kts

• Replace manual maven-publish configuration with com.vanniktech.maven.publish plugin v0.32.0
• Remove 62 lines of manual publishing/signing setup—plugin handles this automatically

gradle.properties

• Add SONATYPE_HOST=CENTRAL_PORTAL for new Maven Central infrastructure
• Add RELEASE_SIGNING_ENABLED=true for artifact signing
• Add POM metadata properties (name, description, license, SCM, developers) consumed by plugin

Publishing behavior

The existing .github/workflows/release.yml is already compatible. It uses publishAllPublicationsToMavenCentralRepository task and provides GPG secrets via environment variables:

• ORG_GRADLE_PROJECT_mavenCentralUsername
• ORG_GRADLE_PROJECT_mavenCentralPassword
• ORG_GRADLE_PROJECT_signingInMemoryKey
• ORG_GRADLE_PROJECT_signingInMemoryKeyPassword

Local builds work without signing credentials. Publishing requires GPG keys (provided in CI).

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
