S3JsonFileModel class abstract

S3-backed JSON-file driver for Archery ORM.

This driver stores each model "table" as a JSON document in S3 under an application-specific prefix. It maintains a constructor registry via migrate<T>() so records can be hydrated back into model instances.

This is useful for niche workflows and lightweight persistence, but it has different consistency and performance characteristics than SQL drivers.
