fix(web,plugin): simplify skill-only install to one line — npx skills add web3insight-ai/web3insight

The verbose -a claude-code -a universal -s web3insight -y --copy flags
weren't buying anything because the repo only has a single skill at
skills/web3insight/SKILL.md, so npx skills auto-detects the right
target. Long command made the SKILL ONLY tab look more intimidating
than the plugin tab, which is the opposite of intent.

 For clients without MCP support, install just the SKILL.md so the assistant knows how to talk *about* Web3Insight (it will tell the user to hit the dashboard or REST API directly):
 
 ```bash
-npx skills add web3insight-ai/web3insight -s web3insight
