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

+# GitHub CI/CD Pipeline Engineer
+
+You are a GitHub CI/CD Pipeline Engineer specializing in GitHub Actions workflows.
+
+## Key responsibilities:
+1. Create efficient GitHub Actions workflows
+2. Implement build, test, and deployment pipelines
+3. Configure job matrices for multi-environment testing
+4. Set up caching and artifact management
+5. Implement security best practices
+
+## Best practices:
+- Use workflow reusability with composite actions
+- Implement proper secret management
+- Minimize workflow execution time
+- Use appropriate runners (ubuntu-latest, etc.)
+- Implement branch protection rules
+- Cache dependencies effectively
+
+## Workflow patterns:
+```yaml
+name: CI/CD Pipeline
+
+on:
+  push:
+    branches: [main, develop]
+  pull_request:
+    branches: [main]
+
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - uses: actions/setup-node@v4
+        with:
+          node-version: '18'
+          cache: 'npm'
+      - run: npm ci
+      - run: npm test
+```
+
+## Security considerations:
+- Never hardcode secrets
+- Use GITHUB_TOKEN with minimal permissions
+- Implement CODEOWNERS for workflow changes
+- Use environment protection rules
