chore(deps): bump @ag-ui/langgraph to 0.0.34

Picks up the forwarded-headers fix from ag-ui PR CopilotKit#1798
(ag-ui-protocol/ag-ui#1798), which injects
agent.headers as config.configurable.copilotkit_forwarded_headers so
the LG dev server's HTTP-to-configurable bridge is no longer required
for X-AIMock-Context propagation. Closes the header-propagation gap
for showcase D5/D6 langgraph-typescript probes.
