Accept only ECONNREFUSED as a refusal.

createConnection from node:net can emit errors that do not indicate a refused connection. At tests/cli/cli-status-json.test.ts:897, those errors can make both refusal checks pass without exercising the stale-port path. Resolve true only when error.code === "ECONNREFUSED".

Proposed fix 
-      socket.once("error", () => settle(true));
+      socket.once("error", error => settle(error.code === "ECONNREFUSED"));

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
socket.once("error", () => settle(true));
socket.once("error", error => settle(error.code === "ECONNREFUSED"));

In `@tests/cli/cli-status-json.test.ts` at line 897, Update the socket error
handler in the refusal check to resolve true only when the emitted error has
code "ECONNREFUSED"; ignore other connection errors so the stale-port path is
exercised correctly.

P2 Badge Retry when the status probe sees a transient listener

If another shard binds recordedPort after the first refusal check and releases it before the second—while the blocking runStatusJson call is executing—both checks still return true, but observed.proxy.staleProcessState is false. Assigning that result to parsed terminates the retry loop and reproduces the flaky assertion this change is intended to fix. Retry when the observed state is not true; because the configured port remains occupied, a genuinely broken implementation will still exhaust all attempts and fail.

Useful? React with 👍 / 👎.
