Development Notes

Standalone auth: Uses its own WeChat QR login, NOT the IAAA flow from info-common
Own session.rs: Stores token, fingerprint, bizuin (different from info-common session format)
Mimics real user behavior with configurable delays to bypass risk controls
Article scraping extracts content to clean Markdown
Multiple output formats: table (default), JSON, JSONL
All user-facing strings in Chinese
Error handling: anyhow::Result with .context("中文描述")
