Refs #472

Same cause as #472, hit by the default output of void gen model. The #472 layout is not fixed here.

void gen model writes db/schema/<name>.ts, re-exports it from db/schema.ts, and the generated file imports sql from void/db.

When db/schema.ts exists, the plugin treats only that file as a schema file. db/schema/<name>.ts gets virtual:void-db, which imports the schema, so the import goes around: db/schema.ts → db/schema/<name>.ts → virtual:void-db → db/schema.ts. In dev, sql is not ready yet and every page that imports void/db returns 500 (TypeError: __vite_ssr_import_1__.sql is not a function). vp build → vp preview works.

To reproduce:

pnpm create void my-app   # React / D1
cd my-app
pnpm add zod
pnpm exec void gen model todos title:string done:boolean
pnpm exec void db generate
pnpm dev                  # / and /api/todos return 500

This PR also treats files under db/schema/ as schema files when db/schema.ts exists. The folder comes from paths.schemaDir, the same path gen model writes to.

Out of scope: the #472 layout (a file outside db/schema/ re-exported from db/schema.ts). Moving the drizzle-orm re-export above the schema import in virtual:void-db makes sql ready in dev for that case too (checked locally), but it makes the import order matter, so it is not in this PR.

Checked:

• plugin-drizzle.test.ts (1 new test, fails without the fix)
• typecheck for void
• an app after gen model: dev (500 → 200) and vp build → vp preview (200 before and after)

14 tests in init.test.ts and 1 in nitro.test.ts fail locally on main too. This PR adds no new failures.
