Describe the changes you've made

Adds Java-agent support to the Keploy Java SDK so Java dynamic dedup can run without application code importing or compiling against Keploy classes.

Key changes:

• Prepares io.keploy:keploy-sdk:2.0.0 as the Java agent artifact.
• Adds premain and agentmain entrypoints for -javaagent usage.
• Adds Java agent manifest attributes for Premain-Class and Agent-Class.
• Keeps the existing coverage socket protocol and JaCoCo integration behind the agent.
• Supports class discovery for Maven/Gradle output, classpath entries, plain jars, Spring Boot jars, servlet/WAR layouts, and custom class directories.
• Keeps Keploy SDK internals out of coverage while still allowing application packages under io.keploy.* to be analyzed.
• Adds a Java-agent smoke script that validates the supported launch and archive layouts.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Code style update (formatting, local variables)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

How did you test your code changes?

• mvn -B -DskipTests package
• ./scripts/smoke-javaagent.sh
• git diff HEAD^ HEAD --check
• The smoke script verifies Java-agent startup, per-test coverage capture, and class discovery across Maven, Gradle, classpath fallback, plain jar, Spring Boot layout, and servlet/WAR layout.
