Restore and persist the package-based link collector with progressive metadata, bounded high-volume updates, safe hydration, visible selection, and complete localization.
Harden download controls, snapshot ordering, history pagination, statistics recovery, settings saves, backup imports, notification persistence, and Windows storage races with regression coverage.
Stream completed metadata checks into the collector while preserving generation-based stale-result protection. Derive row statuses from verified availability, move analysis feedback into the sidebar, center table values under their headers, and keep the header synchronized during horizontal scrolling.
Reintroduce expandable collector packages, background metadata enrichment, filters, selection, and controlled queue transfer. Keep DLC files dropped outside the collector on the direct addContainers path without settings persistence or metadata waits. Protect collector state with stable URL identities, non-degrading metadata merges, and per-URL generations so stale enrichment responses cannot overwrite newer data or resurrect removed links.
