Transcript building gained a withoutAttachmentHooks option to skip attachment hooks

What

When Claude Code rebuilds the transcript sent to the API, a new option called withoutAttachmentHooks lets the caller skip the normal attachment hooks and instead use a plain path when re-serializing a human turn's attachments.

Why

The finding does not say why a caller would want to bypass attachment hooks, only that the option now exists.
