Fix production error where know-your-world game failed to load sessions due to ES module imports in CommonJS context.
**Problem:**
- Validator imported maps.ts at module init time
- maps.ts statically imports @svg-maps/world and @svg-maps/usa (ES modules)
- Server (CommonJS) cannot require() ES modules synchronously
- Error: "Unexpected token 'export'"
**Solution:**
- Make validateMove() async (already supported by GameValidator interface)
- Lazy-load getFilteredMapData() only when needed via dynamic import()
- Prevents ES module loading until validator method is actually called
- Client-side code continues to work normally (bundled by Next.js)
- Mark know-your-world page as force-dynamic to avoid SSR issues
**Changes:**
- GameValidator.validateMove: Now supports Promise<ValidationResult>
- KnowYourWorldValidator: Use getFilteredMapDataLazy() wrapper
- session-manager: Await validator.validateMove()
- know-your-world page: Add dynamic = 'force-dynamic' export
Fixes the "Failed to fetch session" error for know-your-world game.

Implement automatic cursor dampening, super zoom on hover, and quick-escape to make sub-pixel regions (Gibraltar 0.08px, Jersey 0.82px) clickable. Fix crosshair accuracy to match dampened cursor position, add excluded region visualization (gray pre-labeled), and increase unfound region contrast (0.3→0.7 opacity).

Add continent-based filtering for the world map to make the game more playable by reducing visual clutter:
Continent Selection:
- Add continent selector to setup screen (only for world map)
- 7 continents + "All" option: Africa, Asia, Europe, North America, South America, Oceania, Antarctica
- Each continent button shows emoji and name
Map Filtering:
- Filter world map regions by selected continent using ISO 3166-1 country codes
- Calculate bounding box for filtered regions
- Automatically crop and scale viewBox to show only selected continent
- Add 10% padding around continent bounding box for better visibility
Technical Implementation:
- Create continents.ts with comprehensive country-to-continent mappings (256 countries)
- Add getFilteredMapData() function to filter regions and adjust viewBox
- Add calculateBoundingBox() to compute min/max coordinates from SVG paths
- Add selectedContinent field to game state and config (persisted to database)
- Add SET_CONTINENT move type and validator
- Update all map rendering components (StudyPhase, PlayingPhase, MapRenderer)
Benefits:
- Solves "too many small countries" problem on world map
- Allows focused study of specific geographic regions
- Dynamic viewBox adjustment provides optimal zoom level
- Maintains full world map option for comprehensive play

Add new arcade game for testing geography knowledge:
Game Features:
- 4 phases: Setup, Study, Playing, Results
- 3 multiplayer modes: Cooperative, Race, Turn-Based
- 2 maps: World countries, USA states
- Configurable study mode (0, 30, 60, or 120 seconds)
- Return to Setup and New Game options in game menu
- Small region labels with arrows for improved visibility
Map Rendering:
- 8-color deterministic palette with hash-based assignment
- Opacity-based states (20-27% unfound, 100% found)
- Enhanced label visibility with text shadows
- Smart bounding box calculation for small regions
- Supports both easy (outlines always visible) and hard (outlines on hover/found) difficulty
Game Modes:
- Cooperative: All players work together to find all regions
- Race: First to click gets the point
- Turn-Based: Players take turns finding regions
Study Phase:
- Optional timed study period before quiz starts
- Shows all region labels for memorization
- Countdown timer with skip option
Dependencies:
- Add @svg-maps/world and @svg-maps/usa packages
