Publish comparison docs: StructKit vs Cookiecutter vs Copier

[httpdss]

Summary

Add a comparison page that clearly explains when to choose StructKit versus Cookiecutter or Copier.

Why this matters

Developers search for alternatives before adopting a new scaffolding tool. A balanced comparison page can capture high-intent SEO traffic and make StructKit’s differentiators easy to understand.

Scope

• Create a docs article/page: StructKit vs Cookiecutter vs Copier.
• Include a comparison table covering remote content, MCP/AI support, YAML-first definitions, dry-run behavior, hooks, conflict strategies, and template repo requirements.
• Include “choose StructKit when…” and “choose another tool when…” sections.
• Link from README and docs navigation.

Acceptance criteria

• Comparison is honest, specific, and not just marketing copy.
• Page includes practical examples of workflows that StructKit handles well.
• Page has a clear CTA to try an example template.
• README links to the comparison.
