 * Resolve the nearest persisted setup scope by walking upward from `startDir`.

 * Launch-time scope resolution is cwd-sensitive: a project-scoped setup must
 * keep launches inside its tree on the project-local Codex config, so the
 * walk stops at the first ancestor (including `startDir` itself) that has a
 * `.omx/setup-scope.json`. A marker that cannot be parsed stops the walk and
 * yields no scope rather than skipping a nearer setup marker. Returns
 * `undefined` when no marker exists anywhere above `startDir`.
