### Task 2: Multi-Page Token Detection ✅
**Commit:** `e89824db` - feat(detection): implement multi-page token detection system

**What was built:**
- **Twitter $TOKEN detection** - Detects `$BONK`, `$SOL`, etc.
- **Contract address detection** - Solana (base58) and Ethereum (0x) addresses
- **Trading pair detection** - Patterns like `BONK/SOL`, `PEPE/USDT`
- **DetectedTokensList component** - Shows detected tokens in UI
- **Smart context extraction** - Different detection per page type

- `sidepanel/context/PageContextProvider.tsx` - Added detectedTokens field
- `sidepanel/components/DetectedTokensList.tsx` - NEW component
- `sidepanel/chat/ChatInterface.tsx` - Integrated DetectedTokensList

**Detection patterns:**
```typescript
// Twitter tokens
/\$([A-Z]{2,10})\b/g

// Ethereum addresses
/\b(0x[a-fA-F0-9]{40})\b/g

// Solana addresses
/\b([1-9A-HJ-NP-Za-km-z]{32,44})\b/g

// Trading pairs
/\b([A-Z]{2,10})\/([A-Z]{2,10})\b/g
```
