Move the global package disclosure action into a responsive right-aligned toolbar group and disable it for empty queues. Replace the decorative package title with a compact neutral filter group, coordinate disclosure opacity with height transitions, and make contextual help follow combined pointer and keyboard focus state.
Rebuild downloads, link collection, settings, history, and statistics around a responsive desktop shell with compact account and queue tables, contextual navigation, persistent update affordances, unified overlays, and accessible keyboard interactions.
Add safe history-folder reveal IPC, responsive 2560/1920/1366/1120 coverage, deterministic visual fixtures, focused component regressions, and release-tree exclusions for internal working files. Bump the public application version to 2.0.13.
