🎯 Goal

Reduce size of the SDK, improve thread-safety, and reduce future breaking changes by replacing enums

📝 Summary

• raw_representable_over_enum: string enums become RawRepresentable classes, which reduces SDK size and keeps unknown server values
• string_coding_keys: one shared StringCodingKey replaces the per-model CodingKeys enums, which reduces SDK size
• immutable_models: let properties and checked Sendable make generated models thread safe
• number_as_float removed: numbers are Double, matching the JSON
• encodable_only_models, decodable_only_models and codable_models: requests are only Encodable, and responses and events only Decodable, which reduces SDK size

🛠 Implementation

Because the generated models are immutable, FeedAddActivityRequest and ActivityAddCommentRequest now build their generated request when it is sent instead of mutating it. The FEEDS-546 createdAt workaround is removed, since the backend fixed it in July 2025.
