The successful focused deconstruct calls onFocusedContribution which
updates parent state, but never persisted the new collection to
sessionStorage. This meant an immediate reload would lose the
contribution.
Fix: add a useEffect in ReasoningWorkspace that watches the
focusedContributions prop for changes and saves via the existing
saveSession mechanism. A ref guard prevents double-save alongside the
existing updateStatus-success effect.
