Stream live quotes (SSE)

GET 
/v1/stream/quotes

Server-Sent Events stream. Emits the following event types: connected, quote, heartbeat, error. Reconnect on disconnect; events resume from latest-seen timestamp. Heartbeats every 30s keep the connection alive. Tiers without real-time data get the SIP-delayed last trade (about 15 minutes old), polled every 15 seconds, and every connected and quote event carries delayed: true. Real-time tiers get fair market value every second with delayed: false.

Too many open streams for the caller's tier (1 Free, 3 Plus, 10 Pro). details.stream_connections carries the cap. Close a stream or upgrade.
