docs: align Node.js setup versions with engine

[dajiaohuang]

Problem

The setup documentation advertised Node.js versions outside the repository's declared engine range. SETUP_PROMPT.md allowed Node 22.12+, while package.json requires ^22.22.2 || ^24.0.0 || >=26.0.0; README.md said only “Node.js 22+”.

Change

Align the README and setup prompt with the exact package.json contract. This avoids implying unsupported Node 23.x or 25.x versions and keeps the documentation consistent with the existing package configuration.

Fixes #587

Validation

• git diff --check
• pnpm lint (not runnable in the fresh clone because dependencies are not installed; the change is Markdown-only)
