feat: v0.2.0 — BBR congestion control, 0-RTT session resumption, management REST API, fallback server, multi-listener
Architecture:
- BBR-inspired congestion controller (SlowStart/ProbeBandwidth/ProbeRTT phases)
- 0-RTT session resumption with anti-replay ticket validation
- Management REST API (axum): /api/users CRUD, /api/server/status, Bearer auth
- TCP fallback proxy for anti-DPI camouflage (nginx/caddy passthrough)
- Multi-listener: bind to multiple UDP addresses simultaneously
- Per-user traffic stats with atomic counters and limit enforcement
Code quality:
- Structured logging: 0 eprintln in server/core/client, all tracing::{info,debug,warn,error}
- 35 unit tests across congestion, resumption, relay, outbound, obfuscation
- Removed dead code: kex.rs, unused dependencies (async-trait, x25519-dalek, rand_distr)
- Modular server: api.rs, fallback.rs, outbound.rs, relay.rs extracted from monolithic lib.rs
CLI:
- --check: config validation
- --generate-key: secure key generation (hex/base64, batch)
- --links: share link generation from server config
- --init: fallback section in server template
Documentation:
- README rewritten with architecture diagram, API examples, CLI reference
- Wiki: Management-API (EN+RU), Configuration (EN+RU), Home (EN+RU) updated

feat: comprehensive diagnostic logging across all modules
protocol.rs:
- Gap recovery logs: skipped frames count, delivered count, remaining buffer
- Duplicate frame detection with nonce values
- Max reorder window exceeded with gap width
- NACK handling: retransmit success vs frame evicted from history
- Reorder buffer overflow with capacity stats
- Close frame receipt
- Zombie frame eviction count
- sent_history overflow (the root cause of speedtest death)
dispatcher.rs:
- New session authentication with peer IP, session count, replay cache size
- Client roaming detection (old addr -> new addr)
- Handshake rejection reasons: timestamp drift, replay cache full, max sessions
- Protocol errors and tick errors with session context
bridge.rs:
- UDP socket buffer diagnostics (requested vs actual)
- Handshake response size and RTT
- Inbound protocol errors with session index
- Outbound packing errors with stream_id
signal.rs:
- Specific shutdown signal identification (SIGTERM/SIGINT/Ctrl+C/Close/Break)
server lib.rs:
- Startup banner with access key count and ARQ config
- UDP buffer diagnostics
- Relay CONNECT/CLOSE/error always visible (not gated by debug)
- All println! -> eprintln! for proper stderr logging
- Hot-reload prefix fixed [ostp-server] -> [ostp]
