Adds src/subscription.ts: createSubscription() opens a native WebSocket
to {wsUrl}, calls onEvent for each valid inbound message (validated
against WsEventSchema and transformed to SorobanEvent), calls onError on
parse failures and connection errors, and reconnects with exponential
backoff (500ms initial, 30s max) on unexpected close. unsubscribe() closes
the socket and cancels any pending reconnect timer.
TridentClient.subscribeToContract() replaces http(s) with ws(s) in
apiUrl, appends contractId and optional topic0 to the query string, and
delegates to createSubscription.
