//! # Bitfinex Exchange Connector
//!
//! Full implementation of Bitfinex API v2 connector.
//!
//! ## Structure
//!
//! - `endpoints` - URLs and endpoint enum
//! - `auth` - Request signing (HMAC-SHA384)
//! - `parser` - JSON array parsing
//! - `connector` - BitfinexConnector + trait implementations
//! - `protocol` - WsProtocol shim for UniversalWsTransport
//! - `websocket` - BitfinexWebSocket thin wrapper
//!
//! ## Key Differences from Other Exchanges
//!
//! 1. **Array-based responses**: All data returned as arrays, not objects
//! 2. **HMAC-SHA384**: Uses SHA384 instead of SHA256
//! 3. **Microsecond nonces**: Nonces in microseconds, not milliseconds
//! 4. **Symbol prefixes**: `t` for trading pairs, `f` for funding
//! 5. **Signed amounts**: Positive=buy, negative=sell for orders/positions
//! 6. **chanId routing**: WS data frames route by integer chanId, not channel name
