/**
 * Canonical test-file predicate shared by the call-graph builder and the
 * artifact generator. These two must agree: the artifact generator excludes
 * test files from signature extraction and the production edge store, while the
 * call-graph builder marks their nodes `isTest` and derives `tested_by` edges.
 * When the two definitions diverged, test code using directory conventions
 * (tests/, __tests__/) or *Spec.kt/*Test.scala leaked into the production graph
 * (polluting hubs/entry-points/stats) and `tested_by` edges were silently lost.
 *
 * Covers, by language:
 *   JS/TS:        foo.test.ts, foo.spec.tsx, __tests__/foo.ts
 *   Python:       test_foo.py, foo_test.py
 *   Go:           foo_test.go
 *   C/C++:        foo_test.cpp, foo_test.cc, foo_test.cxx
 *   Ruby/PHP:     tests/foo.rb, tests/foo.php (directory convention)
 *   Java/Kotlin:  FooTest.java, FooTests.java, FooIT.java, FooSpec.kt,
 *                 and the Maven/Gradle src/test/ source tree
 *   Scala:        FooTest.scala, FooSpec.scala
