fix(readme): swap 'For Humans' and 'For LLM Agents' installation sections

The installation instructions were incorrectly placed:
- 'For Humans' had the curl command (agent behavior)
- 'For LLM Agents' had the copy-paste prompt (human action)

Now correctly:
- 'For Humans': Copy-paste prompt to give to LLM agent
- 'For LLM Agents': Fetch raw installation guide via curl

Fixed in all 4 language versions (EN, KO, JA, ZH-CN).
