Note

Medium Risk
Telemetry config semantics changed from prior defaults (opt-in categories and monitor/screenshot gating), which can alter what events existing integrations receive without code changes.

Overview
Release 0.64.0 ships OpenAPI-driven updates to browser telemetry: opt-in category capture, an expanded event taxonomy, and refreshed docs on create/update params.

Telemetry categories are now opt-in—only categories explicitly set to enabled: true are captured; omitted categories are off. The default set when enabled: true without per-category settings is documented as control, connection, system, and captcha, with CDP-heavy categories (console, network, page, interaction) and screenshot off unless opted in. BrowserTelemetryCategoriesConfig gains captcha, connection, control, screenshot, and system flags alongside the existing CDP categories.

New typed SSE events include in-VM API calls (api_call), captcha outcomes, CDP and live-view connect/disconnect, service crashes, and OOM kills. Collector-health monitor_* events move from category system to monitor (tied to CDP category capture); monitor_screenshot uses the opt-in screenshot category instead of always-on system behavior described in older docs.

Types and public exports are wired through telemetry.ts, browsers barrels, and api.md; the browser create test now exercises all category flags. Version bumps cover package.json, src/version.ts, changelog, and release manifest.

Firetiger deploy monitoring skipped

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

PRs in the kernel, infra, hypeman, and hypeship repos. kernel is a ~mono repo with many logical services underneath, ensure to focus on the implicated service for the PR

Reason: This is a release PR for kernel-node-sdk (a Node.js SDK), not a deployment to the kernel service itself; clarify which service this release affects or opt in manually for deploy monitoring.

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