Browserbase's sessions API on Browsers

Browserbase's Node.js SDK (@browserbasehq/sdk) works with Runtime Browsers when BROWSERBASE_BASE_URL is set to https://<your API host>/compat/browserbase and BROWSERBASE_API_KEY to a Runtime API key. POST /v1/sessions returns a running session with its connectUrl (the browser's Chrome DevTools Protocol WebSocket URL), GET /v1/sessions/{id} and GET /v1/sessions read and list sessions (a list of more than 100,000 sessions returns 400), and POST /v1/sessions/{id} with status: "REQUEST_RELEASE" ends one. Fields and operations not yet supported (region, keepAlive, proxies, contexts, debug URLs, recordings) return 400 or 404 instead of being ignored.
