v0.27.0

New Features

• React introspection - First-class React DevTools integration with new react tree, react inspect <fiberId>, react renders start|stop, and react suspense commands for full component-tree visibility, per-fiber props/hooks/state inspection, render profiling with mount/re-render counts and change details, and Suspense boundary classification with root-cause grouping and recommendations. React DevTools hook is vendored (MIT) and embedded in the binary with zero runtime dependencies (#1257)
• Web Vitals - New vitals [url] command that reports Core Web Vitals (LCP, CLS, TTFB, FCP, INP) plus React hydration phases for any page (#1257)
• SPA navigation - New pushstate <url> command for client-side SPA navigations without a full page load (#1257)
• Init scripts and feature flags - New --init-script <path> flag (repeatable; env AGENT_BROWSER_INIT_SCRIPTS) to register scripts before first navigation, and --enable <feature> flag (repeatable; env AGENT_BROWSER_ENABLE) for built-in init scripts such as react-devtools (#1257)
• Network route resource type filter - network route now accepts --resource-type <csv> to filter intercepted requests by CDP resource type (#1257)
• cURL cookie import - cookies set --curl <file> auto-detects JSON, cURL, and Cookie-header formats for bulk cookie import (#1257)
• Dashboard proxy support - The observability dashboard now works from proxied origins via a same-origin proxy, enabling deployment behind reverse proxies and path-based routing (#1111)

Bug Fixes

• Fixed doctor command generating duplicate check ids when called multiple times in the same process (#1330)

Infrastructure

• Switched npm publishing to trusted publishing via GitHub Actions OIDC, removing the need for manually managed npm tokens (#1273)
