Fix PlatformClassLoadListener method signature mismatches

[sfloess]

Part of #431: Complete SDLC automation and fix classloader-java API compatibility

Problem

PlatformClassLoadListener.java has method signatures that no longer match the interface contract in classloader-java v2.0. This causes compilation failures.

Location

• platform-classloader/src/main/java/org/flossware/platform/classloader/PlatformClassLoadListener.java (lines 44, 60, 65)

Tasks

• Compare current method signatures against classloader-java v2.0 interface definitions
• Update method signatures to match the new interface contract
• Verify behavior is preserved (parameter mapping, return types)
• Update any related tests

Acceptance Criteria

• PlatformClassLoadListener correctly implements the classloader-java v2.0 interface
• All method signatures match the interface contract
• Module compiles without -Dmaven.compiler.failOnError=false workaround
