v0.54.0

Added

• Liquid Glass Navigation: Sidebar and mobile bottom bar now feature a sliding glass pill indicator that animates to the active entry.
• Custom nav icons: public/nav-icons.js provides a full set of monoline SVG icons for all navigation entries, built entirely with the DOM API (createElementNS) — no innerHTML.
• Desktop hover preview: Hovering an inactive sidebar entry shows the destination indicator at 50 % opacity before navigation.
• Household section label: A "Haushalt" section heading appears between the four primary entries (Dashboard, Calendar, Tasks, Notes) and the module entries in the sidebar.
• Locale key nav.section.household: Added to all 16 supported locale files.
• Accessibility: Navigation animations are suppressed when prefers-reduced-motion is active; glass effects are disabled when prefers-reduced-transparency is active.
• Lucide icon fallback for any navigation entry that lacks a custom SVG.
