feat: compact breadcrumb menu + 'X more' Notion-style in workspace

1. Compact breadcrumb hover menu:
   - Reduced font-size: header-breadcrumb 14→13px, breadcrumb-link 14→13px
   - Dropdown menus: fd-nav-menu min-width 240→200px, padding reduced
   - fd-nav-item: padding 6px8→4px6, font 14→13px, gap 8→6px
   - fd-nav-section: font 11→10px, padding reduced
   - fd-nav-ico: size 16→14px, width 20→18px
   - fd-nav-arrow: size 16→14px, margin-left 4→2px

2. 'X more' Notion-style (tree view):
   - Shows first 5 items in displayTree, hides rest
   - 6th item shows 'X more...' with count of remaining items
   - Click to expand and show all items
   - 'Show less' button to collapse back to 5
   - showAll state auto-resets on folder navigation, sort, filter
   - Styling: semi-transparent hover effect on ws-more-item
