fix(extraction): classify RAR directories without losing collision safety

Use WinRAR's directory-attribute listing as a counted type source so bare folder entries remain valid while file-directory aliases are still rejected.

Emit only removed for successfully deleted JVM partial outputs so asynchronous consumers preserve the original archive error instead of reporting a stale missing file.
