fix(extraction): make manual archive workflows deterministic

Scope selected item runs and stop mutations precisely, attach hybrid work to the active run, retain password progress, and report finalization with real percentages.

Drain stale post-processing before manual extraction, allow package and child extraction with open siblings, retry nonterminal hybrid archive attempts, and replace misleading aggregate retry counts with actionable conversion status.
