Uses google-genai + GEMINI_API_KEY instead of the Anthropic SDK, per
product decision to run the server-fallback LLM on Gemini. Same
prompt contract and escalation behavior; only the client/env var
name changed. README documents where to actually set the key.
generate_draft.py takes a few style-exemplar messages plus recent
conversation context and drafts a reply via LLM call (the server
fallback path from tech-design.md §2), with escalation baked into
the system prompt for money/appointment/emotional content. Verified
prompt construction against a real corpus dialogue and hand-compared
a generated draft to the withheld real reply (README "샘플 검증") --
no API key in this session, so the live call itself is untested.
Consolidates the AI-Hub "한국어 SNS 멀티턴 대화" TL/VL zip parts into
clean train/val JSONL (142,575 dialogues), with a QA cross-check
against the raw TS/VS source. Script and docs only -- the dataset
itself stays out of git per .gitignore, both for size and because
AI-Hub's terms restrict redistribution.
