feat(xueqiu): make primary args positional (#213)

- search: query → positional
- stock: symbol → positional
- earnings-date: symbol → positional
- Fix build-manifest scanYaml to preserve positional field

Usage:
  opencli xueqiu search '茅台'
  opencli xueqiu stock SH600519
  opencli xueqiu earnings-date SH600519
