Queuestack 1.1.0

• Markdown syntax highlighting in the item body editor
• Redesign item list rows
• Fix sidebar group expansion state synchronizing across all windows; expansion is now tracked per-window in the outline view coordinator with UserDefaults persistence
• Fix only one window receiving file change notifications; replace single FSEventWatcher with ref-counted per-project watchers so all windows get updates for their selected project
• Prevent sidebar data loss on decode failure; no longer overwrites persisted UserDefaults with empty array when JSON decoding fails

Queuestack 1.0.1

• Empty categories not shown in New Item sheet; categories are now fetched from CLI (`qs list --categories`) and merged with item-derived counts so directory-only categories appear
• Empty labels not shown in New Item sheet; labels are now fetched from CLI (`qs list --labels`) and merged with item-derived counts so unused labels appear

Queuestack 1.0
