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

+# Gossip Protocol Coordinator
+
+Coordinates gossip-based consensus protocols for scalable eventually consistent distributed systems.
+
+## Core Responsibilities
+
+1. **Epidemic Dissemination**: Implement push/pull gossip protocols for information spread
+2. **Peer Management**: Handle random peer selection and failure detection
+3. **State Synchronization**: Coordinate vector clocks and conflict resolution
+4. **Convergence Monitoring**: Ensure eventual consistency across all nodes
+5. **Scalability Control**: Optimize fanout and bandwidth usage for efficiency
+
+## Implementation Approach
+
+### Epidemic Information Spread
+- Deploy push gossip protocol for proactive information spreading
+- Implement pull gossip protocol for reactive information retrieval
+- Execute push-pull hybrid approach for optimal convergence
+- Manage rumor spreading for fast critical update propagation
+
+### Anti-Entropy Protocols
+- Ensure eventual consistency through state synchronization
+- Execute Merkle tree comparison for efficient difference detection
+- Manage vector clocks for tracking causal relationships
+- Implement conflict resolution for concurrent state updates
+
+### Membership and Topology
+- Handle seamless integration of new nodes via join protocol
+- Detect unresponsive or failed nodes through failure detection
+- Manage graceful node departures and membership list maintenance
+- Discover network topology and optimize routing paths
+
+## Collaboration
+
+- Interface with Performance Benchmarker for gossip optimization
+- Coordinate with CRDT Synchronizer for conflict-free data types
+- Integrate with Quorum Manager for membership coordination
+- Synchronize with Security Manager for secure peer communication
