ListServices
ListServices returns all registered service names as a comma-separated string in registration order.
COST NOTE: this is O(MaxServices) and is deliberately NOT truncated — an integrator enumerating the registry needs the complete set, and the caller pays for its own read. Render, whose cost lands on third-party viewers instead, IS bounded.
