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

 This file provides guidance to Claude Code when working with the gmgn-cli plugin.
 
+## CRITICAL RULE — Read This First
+
+**ALL queries about GMGN data MUST use `gmgn-cli` via the skills below.**
+
+This includes: trending tokens, token info, security checks, K-line / price history, wallet holdings, KOL trades, Smart Money trades, swaps, and any other on-chain data.
+
+**NEVER do any of the following to fetch GMGN data:**
+- Web search (e.g. searching "gmgn trending solana")
+- WebFetch / curl to gmgn.ai or any gmgn domain
+- Browser automation or scraping
+- Any method other than `gmgn-cli`
+
+**Why:** The gmgn.ai website requires login, uses dynamic rendering, and does not expose structured data. The CLI is the only correct and supported method. If you attempt to scrape the site, you will get no data or be blocked.
+
+**When a user asks anything about GMGN data — always invoke the matching skill and run the CLI command. No exceptions.**
+
 ## Project Overview
 
 This is a **Claude Code plugin** — a collection of GMGN OpenAPI skills for on-chain operations. It provides CLI tools and skills for token queries, market data, wallet portfolio analysis, and swap execution across sol / bsc / base.

 | `gmgn-token` | Token info, security, pool, holders, traders | User asks about a token's price, market cap, security risk, liquidity pool, top holders, or top traders; user wants to research a token before buying; user asks "is this token safe", "who holds this token", "what's the liquidity" |
 | `gmgn-market` | K-line / candlestick market data + trending tokens + newly launched launchpad tokens | User asks for price history, chart data, OHLCV candles, trading volume over time; user wants to analyze price trends; user asks "show me the 1h chart", "what was the price last week", "give me kline data for this token"; user wants to discover hot or trending tokens; user asks "what tokens are trending", "show me top tokens by volume", "find hot tokens on SOL"; **user asks about newly launched tokens, fresh tokens, latest tokens on launchpads** — e.g. "show me new tokens on pump.fun", "what tokens just launched on SOL", "find newly created tokens", "latest tokens on letsbonk" → use `market trenches --type new_creation` |
 | `gmgn-portfolio` | Wallet holdings, activity, trading stats, token balance | User asks about a wallet's holdings, P&L, transaction history, trading statistics, or token balance; user wants to analyze a wallet; user asks "what tokens does this wallet hold", "show me recent trades", "what's the win rate of this wallet" |
+| `gmgn-track` | Track trade activity of wallets I follow, KOL trades, Smart Money trades across chains | User asks about trades from wallets they follow; user wants to see what KOLs or Smart Money are buying/selling; user asks "show me what wallets I follow have traded recently", "what are KOLs buying", "show me smart money moves on BSC" |
 | `gmgn-swap` | Token swap execution + order status query | User wants to swap tokens, execute a trade, or check an order status; user asks "swap SOL for USDC", "buy this token", "check my order"; **requires private key configured in `.env`** |
