Make the helper test runnable on Node v22.16.

The declared Node engine permits v22.16, but this test launches bin.ts through process.execPath without a TypeScript loader or type-stripping flag. Node v22.16 requires --experimental-strip-types for that entrypoint. On that supported version, the child exits before it returns a token, so the helper assertions fail. Invoke a built entrypoint or supply the required execution mode and account for its diagnostic output. (nodejs.org)

Review comment at @apps/server/src/provider/CodexManagedRuntime.test.ts around
lines 218 - 220:
Update the child-process arguments in the helper test so Node v22.16 can execute
the TypeScript entrypoint at bin.ts, either by invoking a built entrypoint or
enabling the required type-stripping mode. If using that mode, handle its
diagnostic output so the test still extracts the returned token correctly.
