fix(extraction): harden daemon termination and drain deadlines

Prevent aborted daemon waiters and pre-aborted requests from spawning one-shot JVM children. Ignore buffered request completion after abort or timeout so permits and disk leases remain owned until real daemon close. Keep incomplete shutdown operations and leases alive past the shared deadline while returning explicit drain status, and make multipart reservations fail closed whenever any deduplicated member size is unknown. Add real daemon boot, busy, abort, timeout, DONE race, deadline, and reservation regression coverage.
