feat(module): add agent skills installation

[onmax]

Summary

• After nuxt module add, check if module exposes agent skills via meta.agents.skills
• Prompt user to install skills using npx skills add
• Piped stdio to show our own @Clack spinners

Related

• Depends on feat(schema): add agent skills types to ModuleMeta nuxt#34187 (schema types)

Test plan

• Add module with skills config → prompts to install
• Add module without skills → shows "No skills found"
• Decline install → skips skill installation
