naver-news-briefing

Use the CLI script at scripts/naver_news_briefing.py.

Onboarding

Treat Naver Search API credentials as mandatory before the first real use.
Tell the user early that search/briefing/watch flows will fail until client_id and client_secret are stored.
If the user has not completed setup yet, direct them to run:
- python scripts/naver_news_briefing.py setup --client-id ... --client-secret ...
- python scripts/naver_news_briefing.py check-credentials --json
Present setup as the first-run path, not an optional advanced step.
When helping with installation or first use, mention that credentials are stored in data/config.json and use DPAPI-backed secret storage on Windows when possible.
