Add conditional module: JUnit conditional test execution on 6.1.3 (JDK 25)

Fixtures for the OS, JRE, system property, environment variable and EnabledIf
conditions plus a custom ExecutionCondition, run through the JUnit Platform
launcher (in-process and in child JVMs) to capture real skip reasons; skipped
versus aborted lifecycle; stacking, class-level skips and the deactivate switch;
the 2025 article's code compiled as published; and a javap comparison of the
condition package in 5.14.4 and 6.1.3.
