Summary
ACP requests now carry traceparent and tracestate headers, with server spans covering all 13 implemented agent protocol handlers. The release also adds lint checks for inefficient Go patterns and preserves TUI scrollback during partial tool calls.
Why it matters
Trace context makes multi-step agent execution easier to correlate across services, which is necessary for diagnosing latency and failed tool calls.
