CodeBench: plaintext-speksi pienille malleille

- spec-plain.md: "entity Author (authors): name string, email string"
- extractPlainSpec() parseri plaintext → {entities, relationships}
- Small-profiili käyttää plain-formaattia, large JSON
- specText muuttuja: plaintext tai JSON prompteihin
- Ei voi mennä syntaktisesti rikki kuten JSON

+FORMAT (one entity per line):
+project: project-name
+entity EntityName (table_name): field1 type, field2 type, field3 type=default
+entity ChildName (table_name): field1 type, parent_id int->ParentName, field2 type
+
+TYPES: string, text, int, float, bool, date, datetime
