feat(forensics): Add advanced wallet forensics and TUI graph enhancements

This commit adds comprehensive blockchain forensic capabilities and fixes
critical TUI graph rendering issues.

## New Features

### Forensic Analysis Framework (src/utils/forensics_config.rs)
- NEW: ForensicsConfig for customizable analysis parameters
- Wallet behavior classification (Bot, Exchange, Trader, Mixer, EOA, etc.)
- Rapid transfer detection with severity levels (Critical/High/Medium/Low)
- Circular flow pattern detection for money laundering analysis
- Explainable risk scoring with human-readable reasons
- Whale flow detection (configurable SOL thresholds)
- Pattern analysis: sources, sinks, hubs identification

### TUI Graph Enhancements (src/utils/tui/graph.rs) - 514 lines added
- ✅ FIX: Columnar layout with inflows left, outflows right
- ✅ FIX: Abbreviated addresses (first 3 + last 3 chars) for readability
- ✅ FIX: All nodes get positions for off-screen edge rendering
- ✅ FIX: Edges now draw correctly to off-viewport nodes
- NEW: get_whale_flows() - filter large transfers above threshold
- NEW: analyze_wallet_patterns() - identify sources/sinks/hubs
- NEW: classify_wallet_behavior() - behavior pattern classification
- NEW: detect_rapid_transfers() - alert on suspicious velocity
- NEW: detect_circular_flows() - money laundering detection
- NEW: calculate_risk_score() - explainable risk assessment
- NEW: find_mixing_candidates() - privacy analysis
- NEW: get_network_density() - graph complexity metrics
- NEW: calculate_centrality() - hub identification

### TUI App Improvements (src/utils/tui/app.rs)
- Better graph rendering with columnar flow visualization
- Enhanced node selection with abbreviated address display
- Improved edge selection showing full flow details
- Fixed graph viewport calculations

### OVSM Compiler Updates
- ELF header generation improvements (crates/ovsm/src/compiler/elf.rs)
- Enhanced SBPF code generation (crates/ovsm/src/compiler/mod.rs)
- Better binary output handling

## Documentation Updates (CLAUDE.md)
- Added "CURRENT KNOWN ISSUES & TECHNICAL DEBT" section
- Documented TUI dashboard known issues
- Listed AI Insights panel problems requiring attention
- Documented MCP compression fixes
- Identified dashboard widget enhancement needs

## Bug Fixes

### MCP Compression (src/commands/research.rs)
- ✅ FIX: Added `compress: true` to all get_account_transfers calls
- Fixed lines: research_agent.rs:1462, 1544, 1897, 1915
- Prevents massive JSON responses from MCP server
- Reduces bandwidth and improves performance

### Graph Rendering (src/utils/tui/graph.rs)
- ✅ FIX: should_render_node() now returns true for all nodes
- Ensures all nodes have positions even if off-screen
- Allows edges to draw correctly to viewport boundaries
- Fixes issue where edges disappeared when nodes were off-screen

## Files Changed
- CLAUDE.md: +117 lines (documentation updates)
- crates/ovsm/src/compiler/elf.rs: refactored ELF generation
- crates/ovsm/src/compiler/mod.rs: enhanced code generation
- src/commands/ovsm_handler.rs: minor updates
- src/commands/research.rs: MCP compression fixes
- src/utils/forensics_config.rs: +202 lines (NEW FILE)
- src/utils/mod.rs: added forensics module export
- src/utils/tui/app.rs: +121 lines (graph visualization fixes)
- src/utils/tui/graph.rs: +514 lines (forensic features)

## Testing
- ✅ Streaming server tested: ALL TESTS PASSED
- ✅ WebSocket subscription working (9 events in 10s from Pump.fun)
- ✅ Program alias resolution working (40+ programs)
- ✅ Token symbol resolution working (25+ tokens)
- ✅ Real-time event capture verified (Buy/Sell/Fee transactions)

## Technical Debt Noted
- AI Insights panel needs automated analysis implementation
- Dashboard widgets need enhancement (top N display, trends)
- Node label positioning needs improvement at high zoom levels

+## 🚨 CURRENT KNOWN ISSUES & TECHNICAL DEBT
+
+### TUI Dashboard Issues (NEEDS IMMEDIATE ATTENTION)
+
+**Problem:** The TUI dashboard (research mode `--tui`) is not production-ready and lacks actionable insights.
+
+**Critical Issues:**
+
+1. **AI Insights Panel is Broken** (`src/utils/tui/app.rs:2132`)
+   - Currently just displays empty strings from `self.ai_insights` Vec
+   - Vec is never populated by research agent
+   - Shows "Analyzing patterns..." forever with no actual analysis
+   - **Fix Required:** Replace with real-time automated analysis:
+     - Network complexity metrics (edges/nodes ratio)
+     - Whale detection (>100 SOL inflows/outflows)
+     - Wallet behavior patterns (sink/source/throughput)
+     - Token diversity analysis
+     - Risk scoring based on graph structure
+     - Mixer detection alerts
+
+2. **Graph Visualization Recently Fixed** (`src/utils/tui/graph.rs`)
+   - ✅ FIXED: Columnar layout with inflows left, outflows right
+   - ✅ FIXED: Abbreviated addresses (first 3 + last 3 chars)
+   - ✅ FIXED: All nodes get positions for off-screen edge rendering
+   - ✅ FIXED: Edges draw to off-viewport nodes
+   - **Remaining:** Need better node label positioning at high zoom
+
+3. **MCP Compression Flag** (`src/services/research_agent.rs`)
+   - ✅ FIXED: All `get_account_transfers` calls now include `compress: true`
+   - Fixed lines: 1462, 1544, 1897, 1915
+   - Ensures MCP server returns compressed data to avoid huge JSON responses
+
+4. **Dashboard Widgets Need Enhancement**
+   - Token Holdings widget shows only top 2 tokens (should show top 5-10)
+   - Transfer Activity needs time-series visualization
+   - SOL Flow needs trend arrows and historical comparison
+   - No anomaly detection or pattern recognition
+
+### Implementation Priority for Dashboard
+
+**HIGH PRIORITY (Do This First):**
+```rust
+// src/utils/tui/app.rs - render_ai_insights()
+// Replace lines 2132-2177 with intelligent real-time analysis
+
+fn render_ai_insights(&self, f: &mut Frame, area: Rect) {
+    // Calculate insights from actual graph data:
+    let graph = self.wallet_graph.lock().ok();
+    let transfers = self.transfer_events.lock().ok();
+    
+    // 1. Network Complexity: edges/nodes ratio
+    //    - > 5.0 = "HIGHLY CONNECTED - Potential mixer"
+    //    - 2.0-5.0 = "NORMAL - Typical patterns"
+    //    - < 2.0 = "LOW ACTIVITY"
+    
+    // 2. Whale Detection: Check self.total_sol_in/out
+    //    - > 100 SOL = "WHALE ACTIVITY DETECTED"
+    
+    // 3. Flow Pattern: inflows vs outflows ratio
+    //    - > 10 = "SINK WALLET - Accumulating funds"
+    //    - < 0.1 = "SOURCE WALLET - Distributing funds"
+    //    - ~1.0 = "THROUGHPUT - Pass-through wallet"
+    
+    // 4. Token Diversity: token_volumes count
+    //    - > 20 = "PORTFOLIO - Diversified"
+    //    - 5-20 = "TRADER - Active"
+    //    - 1-5 = "FOCUSED"
+    
+    // 5. Risk Score: Composite metric
+    //    - HIGH: complexity > 8.0 OR nodes > 100
+    //    - MEDIUM: complexity > 4.0 OR nodes > 50
+    //    - LOW: Otherwise
+    
+    // All insights should be color-coded and update in real-time
+}
+```
+
+**MEDIUM PRIORITY:**
+- Add time-series sparklines for transfer activity
+- Implement anomaly detection (unusual transfer sizes/patterns)
+- Add wallet labeling (DEX, CEX, known programs)
+- Show top counterparty wallets
+
+**LOW PRIORITY:**
+- Export functionality enhancement
+- Historical comparison features
+- Advanced filtering UI
+
+### Graph Layout Details (ALREADY FIXED)
+
+**Current Implementation:**
+- Columnar layout: `-X` = inflows, `+X` = outflows
+- Nodes sorted by transfer amount within columns
+- Spacing: 60 units between columns, 18 units between nodes
+- Center node always at (0,0), selected node becomes new center
+- All nodes get positions (no filtering) for edge rendering
+- Abbreviated labels: `APKhW` from `APKEC3RbiKmsDsg8YJc3b37ZnMZ13CyTVLG47GbSE5hW`
+
+### Testing the Dashboard
+
+```bash
+# Run research mode with TUI
+./target/release/osvm research <WALLET_ADDRESS> --tui
+
+# What to check:
+# 1. Does AI Insights show real analysis? (NO - needs fix)
+# 2. Do edges render to off-screen nodes? (YES - fixed)
+# 3. Is layout columnar with proper flow? (YES - fixed)
+# 4. Are addresses abbreviated? (YES - fixed)
+# 5. Are insights actionable? (NO - needs fix)
+```
