Extract two pure helpers so they're testable without zustand/expo: - settings-merge.ts: clampPageSize + forward-compatible mergeStoredSettings (the upgrade path where stored data predates a new notification category must yield the default, not undefined). stores/settings.ts now delegates. - notify-format.ts: sanitizeBody (strip C0/DEL control chars, trim, cap at 200) used for server-supplied notification text. stores/events.ts now imports it. Behavior unchanged; typecheck clean. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
