Actual behavior

Vize's Vapor codegen does not carry the <script setup> body over into the compiled output. Any statement inside <script setup>, such as ref(), computed(), watch(), plain variables is simply missing from the result, and there is no setup() function emitted at all, template falls back to invalid _ctx.<name>

Expected behavior

All <script setup> statements must be preserved inside the component's setup() function, exactly as the reference Vue compiler does
