Attribute-level masking for session replay; stray recordings discarded

1.413.0

Minor Changes

• #4376 2da12b8 Thanks @posthog! - Add attribute-level masking to session replay: maskAttributeFn provides per-attribute control over the final serialized value, while maskAllElementAttributes masks all source DOM string attributes (including rendering attributes and synthesized form values) at the cost of replay fidelity.
