Note

Medium Risk
Adds new browsers.telemetry SSE streaming surface plus new request/response fields (telemetry, chrome_policy) and removes deprecated persistent-browser delete types, which may be breaking for consumers and affects core browser-session APIs.

Overview
Bumps SDK version to 0.56.0 and updates generated artifacts/changelog for the new OpenAPI spec.

Adds a new client.browsers.telemetry.stream() SSE endpoint and exports a large set of typed browser telemetry event payloads; browser sessions can now be created/updated with a telemetry config and include telemetry in responses.

Extends browser session APIs to accept/echo chrome_policy, tightens ManagedAuth.can_reauth_reason into an explicit enum, removes deprecated persistent-browser support (BrowserPersistence, DELETE /browsers by persistent_id, and max_persistent_sessions limit fields), and includes minor docs/test/dependency updates (e.g. tsc-multi upgrade).

Firetiger deploy monitoring skipped

This PR didn't match the auto-monitor filter configured on your GitHub connection:

Any PR that changes the kernel API. Monitor changes to API endpoints (packages/api/cmd/api/) and Temporal workflows (packages/api/lib/temporal) in the kernel repo

Reason: This is an automated release PR with no direct file changes shown; the filter requires monitoring of specific API endpoint and Temporal workflow file changes, which cannot be verified from this PR metadata alone.

To monitor this PR anyway, reply with @firetiger monitor this.
