Fix Maven build configuration issues and remove development artifacts

[Copilot]

This PR resolves several Maven build configuration issues that were causing warnings during compilation and potentially affecting build stability.

Issues Fixed

1. Duplicate Dependencies

• org.json:json dependency: Removed duplicate declaration in shared/pom.xml (lines 161-165 and 179-183 both declared version 20231013)
• httpclient dependency: Removed conflicting version in cli/pom.xml (kept 4.5.14, removed 4.5.13)

2. Deprecated Version Declaration

• openai-gpt3-java service: Changed from deprecated LATEST version to specific version 0.18.2 in shared/pom.xml

3. Development Artifact Cleanup

• AssumptionsTest.java: Removed unnecessary test file that was a development artifact and not part of the production test suite

Before

Maven builds showed multiple warnings:

[WARNING] 'dependencies.dependency.version' for com.theokanning.openai-gpt3-java:service:jar is either LATEST or RELEASE (both of them are being deprecated)
[WARNING] 'dependencies.dependency.(groupId:artifactId:type:classifier)' must be unique: org.json:json:jar -> duplicate declaration of version 20231013
[WARNING] 'dependencies.dependency.(groupId:artifactId:type:classifier)' must be unique: org.apache.httpcomponents:httpclient:jar -> version 4.5.14 vs 4.5.13

After

Clean Maven builds with no dependency-related warnings. All existing tests continue to pass (314 tests in CLI module, 51 tests in shared module).

Impact

• Improved build stability and consistency
• Eliminated Maven warnings that could indicate future compatibility issues
• Cleaner dependency management following Maven best practices
• No functional changes to application behavior

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:

• www.jdeploy.com
  • Triggering command: java -jar /home/REDACTED/work/jdeploy/jdeploy/tests/../cli/target/jdeploy-cli-1.0-SNAPSHOT.jar clean package (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)
