feat: Complete Rust port of WiFi-DensePose with modular crates

Major changes:
- Organized Python v1 implementation into v1/ subdirectory
- Created Rust workspace with 9 modular crates:
  - wifi-densepose-core: Core types, traits, errors
  - wifi-densepose-signal: CSI processing, phase sanitization, FFT
  - wifi-densepose-nn: Neural network inference (ONNX/Candle/tch)
  - wifi-densepose-api: Axum-based REST/WebSocket API
  - wifi-densepose-db: SQLx database layer
  - wifi-densepose-config: Configuration management
  - wifi-densepose-hardware: Hardware abstraction
  - wifi-densepose-wasm: WebAssembly bindings
  - wifi-densepose-cli: Command-line interface

Documentation:
- ADR-001: Workspace structure
- ADR-002: Signal processing library selection
- ADR-003: Neural network inference strategy
- DDD domain model with bounded contexts

Testing:
- 69 tests passing across all crates
- Signal processing: 45 tests
- Neural networks: 21 tests
- Core: 3 doc tests

Performance targets:
- 10x faster CSI processing (~0.5ms vs ~5ms)
- 5x lower memory usage (~100MB vs ~500MB)
- WASM support for browser deployment

+# hook session-end
+
+Cleanup and persist session state before ending work.
+
+## Usage
+
+```bash
+npx claude-flow hook session-end [options]
+```
+
+## Options
+
+- `--session-id, -s <id>` - Session identifier to end
+- `--save-state` - Save current session state (default: true)
+- `--export-metrics` - Export session metrics
+- `--generate-summary` - Create session summary
+- `--cleanup-temp` - Remove temporary files
+
+## Examples
+
+### Basic session end
+
+```bash
+npx claude-flow hook session-end --session-id "dev-session-2024"
+```
+
+### With full export
+
+```bash
+npx claude-flow hook session-end -s "feature-auth" --export-metrics --generate-summary
+```
+
+### Quick close
+
+```bash
+npx claude-flow hook session-end -s "quick-fix" --save-state false --cleanup-temp
+```
+
+### Complete persistence
+
+```bash
+npx claude-flow hook session-end -s "major-refactor" --save-state --export-metrics --generate-summary
+```
+
+## Features
+
+### State Persistence
+
+- Saves current context
+- Stores open files
+- Preserves task progress
+- Maintains decisions
+
+### Metric Export
+
+- Session duration
+- Commands executed
+- Files modified
+- Tokens consumed
+- Performance data
+
+### Summary Generation
+
+- Work accomplished
+- Key decisions made
+- Problems solved
+- Next steps identified
+
+### Cleanup Operations
+
+- Removes temp files
+- Clears caches
+- Frees resources
+- Optimizes storage
+
+## Integration
+
+This hook is automatically called by Claude Code when:
+
+- Ending a conversation
+- Closing work session
+- Before shutdown
+- Switching contexts
+
+Manual usage in agents:
+
+```bash
+# At session end
+npx claude-flow hook session-end --session-id "your-session" --generate-summary
+```
+
+## Output
+
+Returns JSON with:
+
+```json
+{
+  "sessionId": "dev-session-2024",
+  "duration": 7200000,
+  "saved": true,
+  "metrics": {
+    "commandsRun": 145,
+    "filesModified": 23,
+    "tokensUsed": 85000,
+    "tasksCompleted": 8
+  },
+  "summaryPath": "/sessions/dev-session-2024-summary.md",
+  "cleanedUp": true,
+  "nextSession": "dev-session-2025"
+}
+```
