backend/main.py is ~600 lines and mixes request models, DuckDB orchestration, Iceberg conversion, and route handlers.
Proposed split:
models.py — Pydantic request/response modelsduckdb_manager.py — DuckDBManager classiceberg.py — _convert_to_iceberg_query + _validate_iceberg_table helpersroutes.py — FastAPI route handlersmain.py — app factory + lifespan only
No behaviour change. Makes tests (#6) and future changes easier to review.
