Initial commitv0.1.0

NAT-aware Kademlia DHT library for peer-to-peer networks.

Features:
- Distributed key-value storage (iterative FIND_NODE, FIND_VALUE, STORE)
- NAT traversal via DTUN hole-punching and proxy relay
- Reliable Datagram Protocol (RDP) with 7-state connection machine
- Datagram transport with automatic fragmentation/reassembly
- Ed25519 packet authentication
- 256-bit node IDs (Ed25519 public keys)
- Rate limiting, ban list, and eclipse attack mitigation
- Persistence and metrics
- OpenBSD and Linux support

+## [0.1.0] - 2026-03-24
+
+### Added
+
+- Kademlia DHT with iterative FIND_NODE, FIND_VALUE, and STORE operations.
+- NAT type detection (global, cone NAT, symmetric NAT).
+- DTUN hole-punching for cone NAT traversal.
+- Proxy relay for symmetric NAT nodes.
+- Reliable Datagram Protocol (RDP) with 3-way handshake, sliding windows,
+  cumulative ACK, EACK/SACK, retransmission, and graceful close.
+- Datagram transport with automatic fragmentation and reassembly.
+- Ed25519 packet authentication (reject unsigned packets).
+- 256-bit node IDs derived from Ed25519 public keys.
+- Address advertisement for routing table updates.
+- Rate limiting per source address.
+- Ban list for misbehaving peers.
+- Eclipse attack mitigation via bucket diversity checks.
+- Persistence for routing table and DHT storage.
+- Metrics collection (message counts, latency, peer churn).
+- Configurable parameters via `Config` builder.
+- Event-based API for async notification of DHT events.
+- OpenBSD (`kqueue`) and Linux (`epoll`) support via mio.
+- Examples: `join`, `put_get`, `dgram`, `rdp`, `two_nodes`, `network`,
+  `remote_get`, `tesserasd`.
+- Integration, scale, and lossy-network test suites.
+- Fuzz harness for wire protocol parsing.
+- Benchmark suite.
