The KDoc-section parser added for the K2/FIR frontend caught `com.intellij.openapi.progress.ProcessCanceledException` by type in order to rethrow it (a control-flow exception that must never be swallowed) before the general `catch (Exception)` fallback. That compile-time type reference is not resolvable on every supported Kotlin compiler version: the IntelliJ classes bundled in the compiler-embeddable classpath vary across the versions in `versions.bzl`. It compiled under 2.3.20 and 2.4.0 (so the language-test builds were green) but failed the internal extractor build with `unresolved reference 'ProcessCanceledException'`. Match the exception by class name instead of by type. This keeps the exact same behaviour (the cancellation exception is still rethrown, everything else is logged and yields null) while removing the only compile-time reference to a class that is not present on every version's classpath. Verified the standalone extractor now builds for 1.9.20-Beta, 2.0.0-RC1 and 2.4.0. No expected-output changes: the runtime behaviour is unchanged.
