Note

Medium Risk
Medium risk: adds a large new Browsers.Telemetry SSE streaming surface plus new request/response fields (telemetry, chrome_policy) that affect browser session creation/update and JSON (un)marshalling.

Overview
Bumps the SDK to v0.57.0 and updates release metadata/docs (CHANGELOG.md, README.md, api.md).

Adds browser telemetry/event streaming support via a new client.Browsers.Telemetry.Stream SSE endpoint and a large set of new event/config types (BrowserTelemetryConfig*, BrowserTelemetryEventUnion, etc.), and wires the telemetry subservice into BrowserService.

Extends browser session APIs to accept and/or return new fields: chrome_policy on create (and echoed in session responses) and telemetry configuration on create/update (and returned on session objects). Updates related tests and expands shared/constant event-type constants.
