vue-component-meta and TypeScript compiler bundled into production SSR output

[fago]

The prepareComponentIndex server route imports vue-component-meta (which depends on the full TypeScript compiler, ~8.7 MB) via dynamic import().

This is not really necessary because:

1. The component-index.json is pre-generated during build and served as a static asset
2. The server route with prepareComponentIndex is only needed for dev mode regeneration
3. Even when the endpoint is used at runtime, it should gracefully handle missing TypeScript

Impact:

• The node-server preset ships TypeScript in .output/server/node_modules/ (13 MB) even though it's never used at runtime
