fix(baoyu-post-to-wechat): fix regressions from Windows compatibility PR

- Fix broken md-to-wechat-fixed.ts/wechat-article-fixed.ts filename
  references that cause runtime crash (files were never renamed)
- Restore frontmatter quote stripping for title/summary values
- Restore --title CLI parameter functionality (was silently ignored)
- Fix summary extraction to properly skip headings, quotes, lists
- Fix argument parsing to reject single-dash args as file paths
- Remove debug console.error logs left from development
