Add nuxt-skills and update auto quotes to use new policy API structure

- Add nuxt-skills (vue, nuxt, nuxt-ui) to .claude/skills/
- Create useCustomerSelection() composable for managing insured/buyer selection
- Create usePolicyApi() composable for policy API operations
- Update auto quote components to use insured/buyer instead of client
- Update vehicle fields: remove valorVehiculo, add market_value, requested_value, rc_limits
- Make chassis_number and engine_number optional
- Update auto quote types and composables to match new API structure
- Update auto quote page to submit to policy API with new structure

+# Nuxt 4+ Development
+
+Progressive guidance for Nuxt 4+ projects (v4.3+) with latest patterns and conventions.
+
+## When to Use
+
+Working with:
+
+- Server routes (API endpoints, server middleware, server utils)
+- File-based routing (pages, layouts, route groups)
+- Nuxt middleware (route guards, navigation)
+- Nuxt plugins (app extensions)
+- Nuxt-specific features (auto-imports, layers, modules)
+
+## Available Guidance
+
+Read specific files based on current work:
+
+- **[references/server.md](references/server.md)** - API routes, server middleware, validation (Zod), WebSocket, SSE
+- **[references/routing.md](references/routing.md)** - File-based routing, route groups, typed router, definePage
+- **[references/middleware-plugins.md](references/middleware-plugins.md)** - Route middleware, plugins, app lifecycle
+- **[references/nuxt-composables.md](references/nuxt-composables.md)** - Nuxt composables (useRequestURL, useFetch, navigation)
+- **[references/nuxt-components.md](references/nuxt-components.md)** - NuxtLink, NuxtImg, NuxtTime (prefer over HTML elements)
+- **[references/nuxt-config.md](references/nuxt-config.md)** - Configuration, modules, auto-imports, layers
+
+**For Vue composables:** See `vue` skill composables.md (VueUse, Composition API patterns)
+**For UI components:** use `nuxt-ui` skill
+**For database/storage:** use `nuxthub` skill
+**For content-driven sites:** use `nuxt-content` skill
+**For creating modules:** use `nuxt-modules` skill
+**For project scaffolding/CI:** use `ts-library` skill
+
+## Loading Files
+
+**Consider loading these reference files based on your task:**
+
+- [ ] [references/server.md](references/server.md) - if creating API endpoints or server middleware
+- [ ] [references/routing.md](references/routing.md) - if setting up pages, layouts, or route groups
+- [ ] [references/nuxt-composables.md](references/nuxt-composables.md) - if using Nuxt composables (useFetch, useRequestURL, etc.)
+- [ ] [references/middleware-plugins.md](references/middleware-plugins.md) - if working with middleware or plugins
+- [ ] [references/nuxt-components.md](references/nuxt-components.md) - if using Nuxt components (NuxtLink, NuxtImg, etc.)
+- [ ] [references/nuxt-config.md](references/nuxt-config.md) - if editing nuxt.config.ts
+- [ ] [references/project-setup.md](references/project-setup.md) - if setting up CI/ESLint/build tools
+
+**DO NOT load all files at once.** Load only what's relevant to your current task.
+
+## Quick Start
+
+```ts
+// server/api/hello.get.ts
+import { z } from 'zod'
+
+export default defineEventHandler(async (event) => {
+  const { name } = await getValidatedQuery(event, z.object({
+    name: z.string().default('world'),
+  }).parse)
+  return { message: `Hello ${name}` }
+})
+```
+
+## Nuxt 4 vs Older Versions
+
+**You are working with Nuxt 4+.** Key differences:
+
+| Old (Nuxt 2/3)    | New (Nuxt 4)                    |
+| ----------------- | ------------------------------- |
+| `<Nuxt />`        | `<NuxtPage />`                  |
+| `context.params`  | `getRouterParam(event, 'name')` |
+| `window.origin`   | `useRequestURL().origin`        |
+| String routes     | Typed router with route names   |
+| Separate layouts/ | Parent routes with `<slot>`     |
+
+**If you're unsure about Nuxt 4 patterns, read the relevant guidance file first.**
+
