Synthetic surrogate key column name for query-materialized tables. MUST match CodeGenLib's
MATERIALIZATION_SURROGATE_COLUMN (materializationAnalysis.ts) — CodeGen creates the column with
this name and the refresher must regenerate it on every rebuild. (A shared low-level home for this
constant is a follow-up; duplicated deliberately to avoid a runtime dependency on the dev-time CodeGenLib.)
