Note

Medium Risk
Adds a new browsers.telemetry SSE streaming surface plus new telemetry/chrome_policy fields on browser create/update responses and params, which may affect API compatibility and runtime behavior for consumers. Remaining changes are versioning/docs/test updates and a build-tool bump (tsc-multi).

Overview
Bumps the SDK to v0.56.0 and updates generated API metadata/changelog.

Adds a new client.browsers.telemetry.stream() method for streaming browser telemetry events over SSE, including a large set of new telemetry event/config types and exports, and documents it in api.md.

Extends browser-related request/response types to support chrome_policy and per-session telemetry configuration (also reflected in browser pool acquire responses and invocation browser listings), and relaxes the projects.create docstring to remove feature-flag gating. Also upgrades tsc-multi and trims a redundant test import.

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.
