alvinfeiandClaude Opus 5.5 16da11f788 feat(sdk): prompts in 11 languages and an explicit language option
Move every LLM prompt that had a zh variant into one registry,
hy_memory/prompts/, with one module per language (en, zh-Hans, zh-Hant,
ja, es, de, pt, fr, ko, ru, id). Call sites look prompts up with
get_prompt(name, language), so a new language needs only a new module.
The en and zh-Hans strings are moved verbatim, a test pins their sha256,
and the old names (prompts_zh.*_ZH, extractor.EXTRACT_SYSTEM_PROMPT, ...)
still import.

Add an optional language: MemoryConfig.language (env MEMORY_LANGUAGE)
as the client default, plus a per-call language= on add / async_add,
add_extracted, finalize_session, evolve and sweep. It goes through
extract and basic profile, reconcile and search query, the coding
extractor and both coding reconcilers with the chain summary, the
episode and topic summaries, and System 2. Codes are validated, with
aliases (zh, zh-CN, zh-TW, zh-HK, pt-BR); an unknown code raises
ValueError. With an explicit language, memories are written in that
language. Without one, the zh/en auto-detection is unchanged. The
server accepts language on /add and /add_extracted.

Agent Memory - Extractor 提取智能体
统一 Prompt 提取: 单次 LLM 调用提取 memory / intentions / basic_info。
- memory: 一切值得长期记忆的信息(偏好/观点/事件/计划/经历/习惯/决定)
- intentions: 用户未来要做的前瞻意图(带 valid_until 截止日)
- basic_info: 结构化基础画像 kv
LLM 只需感知 memory 与 intention 两类,无需感知内部分层(layer)。
另保留 deep_extract (System 2 深度分析) 供后台精炼使用。
