test(bench): add ACME ERP enterprise workload for ambiguity and recommendations
Adds a reproducible multi-schema Postgres bench (crm/sales/finance/inventory/hr) with planted homonyms, business notes/rules seeding, multi-user chat policies, synthetic pg_stat_statements traffic, and a scorer/verdict harness for DeepSQL schema-ambiguity and workload-recommendation quality.
