CodeBench: --convert-model Python→Go pipeline

- 8b generoi Pythonia (osaa sen), 30b konvertoi Go:ksi
- convert-go.md prompti: FastAPI→Chi, SQLAlchemy→database/sql mappaukset
- Koodigenerointi käyttää Python golden+promptia kun convert-model asetettu
- Vaihe [3.5/5] konvertointia varten

+Convert the following Python FastAPI project to Go using Chi router and modernc.org/sqlite.
+
+OUTPUT: Return ALL files with === markers:
+=== go.mod ===
+=== models.go ===
+=== handlers.go ===
+=== main.go ===
+=== handlers_test.go ===
+
+CONVERSION RULES:
+- package main for all files
+- Pydantic models → Go structs with json tags
+- SQLAlchemy ORM → database/sql with raw SQL and RETURNING clause
+- FastAPI routes → Chi router: r.Post("/path", handler(db))
+- Handlers are closures: func handler(db *sql.DB) http.HandlerFunc
+- Depends(get_db) → State passed via closure over *sql.DB
+- HTTPException(404) → http.Error(w, "not found", http.StatusNotFound)
+- POST returns http.StatusCreated (201), DELETE returns http.StatusNoContent (204)
+- sql.ErrNoRows for not-found checks
+- TestClient → httptest.NewServer + setupTestServer helper
+- test.db → sql.Open("sqlite", ":memory:")
+- Empty list: return []Entity{} not nil
+- import _ "modernc.org/sqlite" (pure Go driver, no CGO)
+- import "github.com/go-chi/chi/v5"
+- No markdown fences in output — just raw code
