v2.5.0 — Addon System, Vacay, Atlas, Dashboard Widgets & Mobile Overhaul

The biggest NOMAD update yet. Introduces a modular addon architecture and three major new features.

Addon System:

Vacay — Vacation Day Planner (Global Addon):
- Monthly calendar view with international public holidays (100+ countries via Nager.Date API)
- Company holidays with auto-cleanup of conflicting entries
- User-based system: each NOMAD user is a person in the calendar
- Fusion system: invite other users to share a combined calendar with real-time WebSocket sync
- Vacation entitlement tracking with automatic carry-over to next year
- Full settings: block weekends, public holidays, company holidays, carry-over toggle
- Invite/accept/decline flow with forced confirmation modal
- Color management per user with collision detection on fusion
- Dissolve fusion with preserved entries

Atlas — Travel World Map (Global Addon):
- Fullscreen Leaflet world map with colored country polygons (GeoJSON)
- Glass-effect bottom panel with stats, continent breakdown, streak tracking
- Country tooltips with trip count, places visited, first/last visit dates

- Canvas renderer with tile preloading for maximum performance
- Responsive: mobile stats bars, no zoom controls on touch

Dashboard Widgets:
- Currency converter with 50 currencies, CustomSelect dropdowns, localStorage persistence
