Add Maven repository configuration for publishing to dansplugins.com

[Copilot]

This PR configures the project to publish artifacts to the Dan's Plugins Community Maven repository hosted at dansplugins.com.

Changes

Added a distributionManagement section to pom.xml with the following repositories:

• Releases: https://maven.dansplugins.com/repository/maven-releases/
• Snapshots: https://maven.dansplugins.com/repository/maven-snapshots/

Usage

After this change, the project can be published to the Maven repository using:

mvn clean deploy

Developers will need to configure their Maven credentials in ~/.m2/settings.xml:

<servers>
  <server>
    <id>dpc-maven-repo-releases</id>
    <username>your-username</username>
    <password>your-password</password>
  </server>
  <server>
    <id>dpc-maven-repo-snapshots</id>
    <username>your-username</username>
    <password>your-password</password>
  </server>
</servers>

Notes

• The configuration follows the standard pattern from the dpc-mvn-repo infrastructure
• Since the current version is 2.2.1-SNAPSHOT, artifacts will be published to the snapshots repository
• Release versions (without -SNAPSHOT) will automatically be published to the releases repository

Closes #[issue_number]

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:

• hub.spigotmc.org
  • Triggering command: /usr/lib/jvm/temurin-17-jdk-amd64/bin/java --enable-native-access=ALL-UNNAMED -classpath /usr/share/apache-maven-3.9.11/boot/plexus-classworlds-2.9.0.jar -Dclassworlds.conf=/usr/share/apache-maven-3.9.11/bin/m2.conf -Dmaven.home=/usr/share/apache-maven-3.9.11 -Dlibrary.jansi.path=/usr/share/apache-maven-3.9.11/lib/jansi-native -Dmaven.multiModuleProjectDirectory=/home/REDACTED/work/SimpleSkills/SimpleSkills org.codehaus.plexus.classworlds.launcher.Launcher clean package -DskipTests (dns block)
• jitpack.io
  • Triggering command: /usr/lib/jvm/temurin-17-jdk-amd64/bin/java --enable-native-access=ALL-UNNAMED -classpath /usr/share/apache-maven-3.9.11/boot/plexus-classworlds-2.9.0.jar -Dclassworlds.conf=/usr/share/apache-maven-3.9.11/bin/m2.conf -Dmaven.home=/usr/share/apache-maven-3.9.11 -Dlibrary.jansi.path=/usr/share/apache-maven-3.9.11/lib/jansi-native -Dmaven.multiModuleProjectDirectory=/home/REDACTED/work/SimpleSkills/SimpleSkills org.codehaus.plexus.classworlds.launcher.Launcher clean package -DskipTests (dns block)

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)
