No SDK changes required: internal server-side trait serializer cleanup

[Copilot]

The blueink-core production change (7e494c9) removed the append_legacy parameter from the internal GroupTraits.from_account() call in AccountV2Serializer — a pure server-side implementation detail with no effect on the public API surface.

Analysis

• The Python SDK has no accounts subclient, no with_traits query parameter handling, and no references to append_legacy or GroupTraits anywhere in the codebase
• The diff does not change any endpoint paths, request parameters, or response schema that the SDK exposes or documents
• No SDK files (source, tests, examples) require modification
