Reorganize: Move all skills to skills/ folder

- Created skills/ directory
- Moved 272 skills to skills/ subfolder
- Kept agents/ at root level
- Kept installation scripts and docs at root level

Repository structure:
- skills/           - All 272 skills from skills.sh
- agents/           - Agent definitions
- *.sh, *.ps1       - Installation scripts
- README.md, etc.   - Documentation

+description: "Use when creating Nuxt modules: (1) Published npm modules (@nuxtjs/, nuxt-), (2) Local project modules (modules/ directory), (3) Runtime extensions (components, composables, plugins), (4) Server extensions (API routes, middleware), (5) Releasing/publishing modules to npm, (6) Setting up CI/CD workflows for modules. Provides defineNuxtModule patterns, Kit utilities, hooks, E2E testing, and release automation."

+# Nuxt Module Development
+
+Guide for creating Nuxt modules that extend framework functionality.
+
+**Related skills:** `nuxt` (basics), `vue` (runtime patterns)
+
+## Quick Start
+
+```bash
+npx nuxi init -t module my-module
+cd my-module && npm install
+npm run dev        # Start playground
+npm run dev:build  # Build in watch mode
+npm run test       # Run tests
+```
+
+## Available Guidance

+- **[references/development.md](references/development.md)** - Module anatomy, defineNuxtModule, Kit utilities, hooks
+- **[references/testing-and-publishing.md](references/testing-and-publishing.md)** - E2E testing, best practices, releasing, publishing
+- **[references/ci-workflows.md](references/ci-workflows.md)** - Copy-paste CI/CD workflow templates

+## Module Types
+
+| Type      | Location         | Use Case                         |
+| --------- | ---------------- | -------------------------------- |
+| Published | npm package      | `@nuxtjs/`, `nuxt-` distribution |
+| Local     | `modules/` dir   | Project-specific extensions      |
+| Inline    | `nuxt.config.ts` | Simple one-off hooks             |
