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

-# Nuxt Content v3
-
-Progressive guidance for content-driven Nuxt apps with typed collections and SQL-backed queries.
-
-## When to Use
-
-Working with:
-
-- Content collections (`content.config.ts`, `defineCollection`)
-- Remote sources (GitHub repos, external APIs via `defineCollectionSource`)
-- Content queries (`queryCollection`, navigation, search)
-- MDC rendering (`<ContentRenderer>`, prose components)
-- Database configuration (SQLite, PostgreSQL, D1, LibSQL)
-- Content hooks (`content:file:beforeParse`, `content:file:afterParse`)
-- i18n multi-language content
-- NuxtStudio or preview mode
-- LLMs integration (`nuxt-llms`)
-
-**For writing documentation:** use `document-writer` skill
-**For Nuxt basics:** use `nuxt` skill
-**For NuxtHub deployment:** use `nuxthub` skill (NuxtHub v1 compatible)
-
-## Available Guidance
-
-Read specific files based on current work:
-
-- **[references/collections.md](references/collections.md)** - defineCollection, schemas, sources, content.config.ts
-- **[references/querying.md](references/querying.md)** - queryCollection, navigation, search, surroundings
-- **[references/rendering.md](references/rendering.md)** - ContentRenderer, MDC syntax, prose components, Shiki
-- **[references/config.md](references/config.md)** - Database setup, markdown plugins, renderer options
-- **[references/studio.md](references/studio.md)** - NuxtStudio integration, preview mode, live editing
-
-## Usage Pattern
-
-**Progressive loading - only read what you need:**
-
-- Setting up collections? → [references/collections.md](references/collections.md)
-- Querying content? → [references/querying.md](references/querying.md)
-- Rendering markdown/MDC? → [references/rendering.md](references/rendering.md)
-- Configuring database/markdown? → [references/config.md](references/config.md)
-- Using NuxtStudio? → [references/studio.md](references/studio.md)
-
-**DO NOT read all files at once.** Load based on context:
-
-- Editing `content.config.ts` → read collections.md
-- Using `queryCollection()` → read querying.md
-- Working with `<ContentRenderer>` or MDC → read rendering.md
-- Configuring database or markdown → read config.md
-- Setting up preview/studio → read studio.md

-## Key Concepts
-
-| Concept         | Purpose                                                           |
-| --------------- | ----------------------------------------------------------------- |
-| Collections     | Typed content groups with schemas                                 |
-| Page vs Data    | `page` = routes + body, `data` = structured data only             |
-| Remote sources  | `source.repository` for GitHub, `defineCollectionSource` for APIs |
-| queryCollection | SQL-like fluent API for content                                   |
-| MDC             | Vue components inside markdown                                    |
-| ContentRenderer | Renders parsed markdown body                                      |
