docs(skills): optimize descriptions for vector search and keyword search

Rewrote all 6 SKILL.md descriptions to improve discoverability on
clawhub.ai via both vector (semantic) and keyword search:
- gmgn-token: add "due diligence", "is it a rug", "dev wallet", "before buying" semantics
- gmgn-market: clarify "without a specific token address" to distinguish from gmgn-token; add "pumping", "fresh listings"
- gmgn-portfolio: add "by address", "decide whether to copy-trade" trigger context
- gmgn-swap: add "single swap" vs multi-wallet distinction; clarify execution verbs
- gmgn-track: add "alpha signals", "on-chain alpha"; explicit boundary note vs gmgn-portfolio
- gmgn-cooking: add "bonding curve fair launch", "cook a token", ETH/TON chain support

+description: Get real-time buy/sell activity across Smart Money wallets, KOL (influencer) wallets, and personally followed wallets via GMGN API — ideal for alpha signals, whale tracking, and copy-trading ideas.
