feat: add Nuxt and Vue.js expert agents

[GeoffreyCasaubon]

Summary

Add two new agents for the Vue.js ecosystem:

• nuxt-expert.agent.md — Expert Nuxt Developer agent covering Nuxt 3, Nitro, rendering modes, data fetching, and legacy Nuxt 2 compatibility.
• vuejs-expert.agent.md — Expert Vue.js Frontend Engineer agent covering Vue 3 Composition API, Pinia, Vue Router, TypeScript integration, and legacy Vue 2/Options API compatibility.

Both agents use Claude Sonnet 4.5 and follow existing agent conventions.

Checklist

• Run npm install (or npm ci)
• Run npm run build to generate the updated README.md
• Run bash scripts/fix-line-endings.sh to normalize line endings
• All new files have proper front matter
• File names follow the lower-case-with-hyphens naming convention

Pull request overview

Adds new ecosystem-focused agents (Nuxt + Vue.js) and expands the plugin catalog with additional partner agents and several new skills/agents across MCP development, OpenAPI scaffolding, Java/.NET, and context-engineering. The PR also standardizes many plugin manifests by switching agent/skill references to directory paths and removing trailing slashes.

Changes:

• Add nuxt-expert.agent.md and vuejs-expert.agent.md expert agents.
• Add multiple new agent/skill markdown files across various plugins/* packages (partners, MCP development, OpenAPI-to-app, etc.).
• Update many plugins/*/.github/plugin/plugin.json manifests (agent paths consolidated to ./agents; skill paths normalized).
