/* Typed relational row machinery for the common operator tree.
Stable generational identities, dense swap_remove storage, borrowed row
shapes, concrete index strategies, and the operator protocol. Scoring
terminals live under `constraint::relational`. Nothing here introduces a
public erased graph API: every type is concrete and monomorphized.
