"""Unit: agent NO_PROXY value builder (PR #25 follow-up).

claude-code's HTTP MCP client must bypass pipelock for the supervise
sidecar — long-poll tool calls would hit pipelock's idle timeout
otherwise. This test pins the rule: localhost always; supervise iff
the supervise sidecar is in the plan."""
