feat: implement icon extraction, market prices, and GUI dialogs

- icon_manager.py: Download item icons from EntropiaWiki with caching
- market_prices.py: Manual price tracking and profit calculators
- icon_price_dialogs.py: GUI for browsing icons and managing prices
- FEATURE_RESEARCH.md: Comprehensive feature research document
- Multiple icon sizes (32x32, 64x64, 128x128)

+# Lemontropia Suite - Feature Research & Implementation
+
+## 🎨 Icon Extraction System (NEW)
+
+### Implementation: `modules/icon_manager.py`
+
+**What it does:**
+- Downloads item icons from EntropiaWiki
+- Caches icons locally for fast access
+- Multiple size presets (32x32, 64x64, 128x128)
+- Batch export to PNG
+- Failed lookup tracking (avoids repeated requests)
+
+**Usage:**
+```python
+from modules.icon_manager import IconManager
+
+icons = IconManager()
+
+# Get single icon
+icon_path = icons.get_icon("ArMatrix BP-25 (L)", size='large')
+
+# Export for use elsewhere
+icons.export_icon("ArMatrix BP-25 (L)", Path("C:/Export/weapon.png"))
+
+# Batch export all gear
+icons.batch_export_icons(
+    ["ArMatrix BP-25", "Ghost Harness", "Regeneration Chip"],
+    Path("C:/Export/GearIcons/")
+)
+```
+
+**Future Enhancements:**
+- [ ] Extract icons directly from game client files (if accessible)
+- [ ] Icon recognition (identify item from screenshot of icon)
+- [ ] Custom icon overlays (add tier, condition indicators)
+- [ ] Icon pack export (zip of all known items)
+
+---
+
+## 💰 Market Price Integration (NEW)
+
+### Implementation: `modules/market_prices.py`
+
+**What it does:**
+- Manual price tracking for frequently traded items
+- Calculate loot value with markup
+- Crafting profitability calculator
+- Hunting profitability analysis
+
+**Features:**
+- Set custom markup % for items
+- Calculate real loot value (not just TT)
+- Track unknown prices (items needing price data)
+- Export price lists
+
+**Usage:**
+```python
+from modules.market_prices import ManualPriceTracker, ProfitCalculator
+
+prices = ManualPriceTracker()
+prices.set_price("Shrapnel", Decimal("100.01"), Decimal("0.01"))  # 100.01% MU
+
+# Calculate hunt profitability
+calc = ProfitCalculator(prices)
+result = calc.calculate_hunting_profit(
+    ammo_cost=Decimal("45.00"),
+    armor_decay=Decimal("5.00"),
+    healing_cost=Decimal("3.00"),
+    loot_items=[
+        ("Shrapnel", Decimal("0.01"), 5000),  # 50 PED
+        ("Iron Stone", Decimal("0.05"), 10),   # 0.5 PED
+    ]
+)
+# Shows: total_cost, loot_mu, profit, return_pct
+```
+
+**Future:**
+- [ ] EntropiaWiki scraping for auto-prices
+- [ ] Price trend graphs
+- [ ] Best time to sell analysis
+
+---
+
+## 📊 Additional Feature Ideas
+
+### 1. **Session Replay System**
+- Record all events during session
+- Replay hunt in timeline view
+- Click on timestamp to see game state
+- Share "run" files with friends
+
+### 2. **Comparative Analytics**
+- Compare hunting spots efficiency
+- Compare weapon DPP over time
+- Best time of day analysis
+- Day-of-week performance
+
+### 3. **Predictive Loot System**
+- Machine learning model
+- Predict next global timer
+- Estimate remaining mobs until global
+- (Based on EU's RNG patterns)
+
+### 4. **Mining Assistant**
+- Claim depth/radius tracker
+- Claim type recording (lgt, oily, etc.)
+- Mining run profitability
+- Resource hotspot mapping
+
+### 5. **Event Calendar Integration**
+- Track Mayhem, Easter, Summer events
+- Personal event statistics
+- Event loot analysis
+- Compare event vs regular hunting
+
+### 6. **Bankroll Management**
+- Track PED deposits/withdrawals
+- Set daily/weekly hunting budgets
+- Alert when approaching limits
+- ROI tracking over time
+
+### 7. **Social Features**
+- Friend comparison (who got biggest global?)
+- Guild/team shared stats
+- Loot leaderboards
+- Competition mode
+
+### 8. **Export Capabilities**
+- CSV export for Excel analysis
+- PDF session reports
+- YouTube video metadata generation
+- Stream overlay integration (OBS)
+
+### 9. **Mobile Companion App**
+- Discord bot commands
+- Telegram status updates
+- Mobile alert on big loot
+- View stats on phone
+
+### 10. **Advanced Vision**
+- Read health % from screen
+- Detect claim sizes visually
+- Read chat messages automatically
+- Detect globals without log parsing
+

+
+## 🎯 User Experience Goals
+
+**Powerful but Simple:**
+- Default settings work out of the box
+- Advanced features hidden behind menus
+- Tooltips explain every metric
+- Video tutorials for complex features
+
+**Fast & Responsive:**
+- All operations under 100ms
+- Background data loading
+- Lazy loading for history
+- Cached icons and prices
+
+**Customizable:**
+- Toggle any feature on/off
+- Custom HUD layouts
+- User-defined categories
+- Personal color schemes
+
+---
+
+## 🔐 Security & Ethics
+
+**User Data:**
+- All data stored locally by default
+- Optional cloud sync (encrypted)
+- No telemetry without consent
+- Open source for transparency
+
+**Game Compliance:**
+- Read-only from game (no injection)
+- Respects Entropia Universe EULA
+- No automation/botting features
+- Fair play for all users
+
+---
+
+## 🚀 Next Steps
+
+1. **Test current features** in real hunting session
+2. **Gather feedback** on what's most useful
+3. **Prioritize** based on user needs
+4. **Iterate** quickly on most-wanted features
+5. **Document** everything thoroughly
+
