Fixed

• CLI: feature-usage tracking calls that pull the event name from a property of a tracking helper's input (including destructured or optional parameters) are now detected correctly — previously these could be silently missed during a scan.
• CLI: feature-usage tracking calls that reference a named constant (e.g. an enum member) are now detected correctly, including when the constant is defined in another file.
• CLI: a tracking call using the wrong argument shape (an object where a plain event name is expected) is now consistently ignored, closing an edge case where it could previously be picked up by mistake.
