fix(nuxt): generate nuxt module builder layout

[userquin]

Following with #9, this PR includes:

• use @devframes/nuxt at nuxt module meta (renamed from devframe)
• rename nuxt module to module.ts
• generate dist/types.d.mts
• generate dist/module.json: includes the name, the version (from package.json) and the tsdown for the builder entry (getting tsdown version from package.json devDependencies)
• export ModuleOptions and DevframeNuxtModuleOptions and use ModuleOptions at defineNuxtModule: export type ModuleOptions = DevframeNuxtModuleOptions
• remove exports: true from module build
• change default subpackage export to use ./dist/types.d.mts for types and global types
• hack useRuntimeConfig at nuxt.d.ts
• change how we override baseURL
• client plugin to use the new useRuntimeConfig module augmentation
• updated tsnapi for module: tests/__snapshots__/tsnapi/@devframes/nuxt/index.snapshot.d.ts

NOTE: if we start adding some nuxt stuff in the module (module hooks...), maybe we'll need to switch to nuxt module builder.

maybe we should remove the ^ if present

I need to review the version, maybe we need to load pnpm workspace and find the tsdown version in the correspoding catalog
