The public API version published by the on-page RUM JavaScript agent.
Consumers (e.g. the SDK compat layer) can read this to detect the agent's API version and make
informed decisions (for example, warn when the agent is newer than the SDK knows about) instead of
silently breaking when out of sync. It is undefined for agents that predate API versioning.
