L142 (+CC14): keyed latest-wins reconciler (lib/reconcile.ts, unit-tested)
applies main's authoritative IPC returns in the history/templates/sources
stores, extending the M34 settings pattern; loadSources shares the key so
a slow list read can't clobber a newer mutation result.
L93 (+CC13): settings cards, TerminalView, and LibraryView now reach IPC
only through colocated view-model hooks (useAboutCard/useBackupCard/
useCookiesCard/useSoftwareUpdateCard/useNetworkCard/useTerminalRun) or
store actions (openHighContrastSettings, scheduled-sync on sources) —
no window.api left in components.
