Both the dependency declaration and its catalog entry named
EscapedCoroutineErrors.kt as the sole reason kotlinx-coroutines-test is on the
test classpath. That file is gone, and nothing in the gate -- not ktlint, not
detekt, not lint -- fails on prose naming a deleted file, so this would have
survived as a reference a reader could only resolve through git history.
The dependency itself stays, and for a reason worth restating where it is
declared: `runTest` is what registers the collector callback, so the one test
that deliberately lets an error escape is the scope that receives it.
