feat: add track command group, split follow-wallet/kol/smartmoney from portfolio

- Add new `track` command group with three sub-commands:
  - `track follow-wallet`: monitor trade activity of followed wallets (critical auth)
  - `track kol`: KOL trade records with optional --chain and client-side --side filter
  - `track smartmoney`: Smart Money trade records with optional --chain and client-side --side filter
- Remove follow-wallet, kol, smartmoney sub-commands from portfolio
- Add getKol/getSmartMoney optional chain param in OpenApiClient
- Switch getFollowWallet to criticalRequest (signature auth required)
- Align track follow-wallet options to actual API params (remove unsupported flags)
- Add skills/gmgn-track/SKILL.md with sub-command guide, options, response fields
- Add IMPORTANT notice to all SKILL.md files to prevent AI from scraping gmgn.ai
- Add CRITICAL RULE section to CLAUDE.md to enforce CLI-only data access
- Update Readme.md and Readme.zh.md: add gmgn-track skill, Track CLI section, user tip
