Description

Add coverage for the complete non-interruptive event lifecycle: an event begins in the defined state, starts through PhasedEventManager, can be waited on until it finishes, and ends in the finished state.

Related Issue

Closes #190

Motivation and Context

The existing event tests cover individual start and finish behaviors, but do not assert the state transitions together. This regression test documents the expected lifecycle for event implementations and the event manager.

How Has This Been Tested?

• mvn -s C:/Users/LENOVO/AppData/Local/Temp/omnirush/maven-settings.xml -pl phased-testing-testng -am -Dtest=TestPhasedNonInterruptive -Dsurefire.failIfNoSpecifiedTests=false test
• mvn -s C:/Users/LENOVO/AppData/Local/Temp/omnirush/maven-settings.xml -pl phased-testing-testng -am test
• Targeted run: 29 tests passed, 0 failures, 0 errors, 0 skipped.
• Full module run: 418 tests passed, 0 failures, 0 errors, 0 skipped.
• git diff --check

Note: the repository's .mvn/settings.xml has a leading blank line before its XML declaration, so Maven was run with a temporary empty settings file to bypass that pre-existing configuration issue.
