New Features

snapshot option for system prompts: Added a snapshot field to SystemPromptPreset and a new SystemPromptCustom typed dict. When snapshot is True, the session keeps the system prompt recorded on its first request, improving prompt-caching behavior across resumed sessions. When False, the prompt is rebuilt on every request, useful for iterating on append text. Requires CLI 2.1.257+ (#1268)

Internal/Other Changes

Updated bundled Claude CLI to version 2.1.273
