PersistDataValue Transformation

Builder for creating a PersistDataValue transformation that stores a value from the dispatch payload (or a constant) into the data layer with a configurable expiry and update policy.

Example usage:

let settings = PersistDataValueSettingsBuilder(id: "persist-user-id")
    .persistFrom(.key("user_id"), to: .key("persisted_user_id"))
    .setExpiryPolicy(.forever)
    .setUpdatePolicy(.keepFirstValue)
    .setScope(.afterCollectors)
    .build()

Defines how a persisted value should behave when a value already exists at the destination. Use this to control whether a new value can overwrite an existing one.
