// A body-local `#run` const of a BRIDGEABLE shape — a scalar, a struct, an
// array, or an `?Array` optional — evaluates and produces its const value.
// These are the common cases that must keep working alongside the issue-0182
// fix (which fails ONLY the unbridgeable-result case, e.g. `[2][]i64`).
//
// Regression (issue 0182): the body-local `#run` fold must not regress the
// bridgeable cases when it learned to fail loudly on an unbridgeable result.
