Startup logging now warns when a telemetry destination matches NO_PROXY and will bypass the egress proxy

What

When Claude Code starts up, it now checks each configured telemetry forwarding destination against the NO_PROXY environment variable. If the egress-boundary proxy mode is active and a destination's URL matches NO_PROXY, it logs a message noting that exports to that host will skip the proxy.

Why

This helps administrators notice when telemetry data is bypassing an intended network proxy, which matters for environments that route all outbound traffic through a controlled egress point.
