Check the child descriptor instead of /dev/stdin

On Linux environments without /dev/stdin, this test can fail even when stdin is correctly ignored. Check descriptor 0 directly so the test still distinguishes a character device from an open pipe.

Suggested fix 

-                executable: "/bin/sh",
+                executable: process.execPath,
                 // An open pipe here would block a CLI that reads stdin until the update times out.
-                args: ["-c", "[ -c /dev/stdin ] || { echo 'stdin is an open pipe' >&2; exit 1; }"],
+                args: [
+                  "-e",
+                  "if (!require('node:fs').fstatSync(0).isCharacterDevice()) { console.error('stdin is an open pipe'); process.exit(1); }",
+                ],

Review comment at @apps/server/src/provider/providerMaintenanceRunner.test.ts
around lines 564 - 599:
Update the stdin check in the skipped test’s `makeTestRunner` configuration so
it inspects child descriptor 0 directly rather than relying on `/dev/stdin`,
which may not exist. Use the Node runtime and verify that descriptor 0 is a
character device, preserving the test’s failure behavior when stdin is an open
pipe.
