Returns recent BridgeEvents from the live preview, ring-buffered (500 entries). Optional filters: source (iframe/host/bridge), level (debug/info/warn/error/system), kind. Pagination via 'since' (event id cursor). bridge-reinstalled events are filtered out by default; pass kind:'bridge-reinstalled' to see them.

Returns recent runtime errors and unhandled-rejection events from the preview iframe. Each error includes message, stack, file, line, column when available. Use this when the user reports a broken preview or you want to see what just crashed.

Asks the connected browser page for a live state snapshot. Kinds: 'form' (all input/textarea/select values, password fields filtered), 'route' (current URL/pathname), 'selection' (highlighted text), 'focus' (focused element selector + value), 'all' (combined). Times out in 800ms if no host page is connected.

Long-poll: blocks until at least one event matching kinds arrives, OR maxWaitMs elapses. Returns the matched events. Use to wait for specific runtime signals (route change, build complete, etc.) without polling get_event_log. Default maxWaitMs=5000, max 30000.

Returns bridge connection state: whether a host page is connected, in which mode (hosted-iframe vs top-level), the preview URL if known, total event count, and bridge version. Use to verify the bridge is actually receiving data before relying on other tools.
