Telemetry was fired as a goroutine then the process exited immediately,
killing it before the HTTP request could complete. Now called
synchronously — sendTelemetry already has a 2s internal timeout so
worst-case latency is unchanged for the user.
Also moves the combined picker into run() so eval products selected
interactively are tagged action=eval with the correct eval_slug instead
of action=interactive with no slug.
Adds What's New changelog section to release notes, auto-generated from
commits since the previous tag.
