chore(spec): deprecate redundant schema-model generation layer

schemas/generated/(174) + src/quant_engine/models/generated/(347) duplicated
the existing runtime/python/core/formulas/generated/ formula-stub system with
a generic metadata wrapper carrying no real computation, validated only by a
file-count gate (validate_schema_model_generation_v1.py). Remove the
generator scripts, generated files, and CI/DAG wiring; keep
schemas/generated/gas_adapter_contract.schema.json, which serves an
unrelated GAS-adapter contract check.
