test_regression_doc2.py — Regression tests per i tre bug Doc2
Copre:
Doc2-1a: cache speculativa mai consultata in _run_direct_tools
Doc2-1b: memory/sync router non montato in main.py
Doc2-1c: SRO session ricreata ad ogni retry (coperto lato TS)
Dipendenze: solo stdlib + moduli backend già presenti.
Non richiede server avviato: test unitari puri.
