// A generic value-param arg that does not fit the param's declared integer type
// (`Box(5_000_000_000)` for `$K: u32`) is a hard error — a clean diagnostic +
// non-zero exit, NOT a silent truncating bind.
//
// Regression (F0.4 attempt 8, item 1): `resolveValueParamArg` bound the folded
// i64 without range-checking the declared type, so an out-of-u32 arg compiled
// and ran. The bind now routes a `u32` count through the shared
// `program_index.foldDimU32` gate (the same one array dims / Vector lanes use),
// so an oversized value is rejected before instantiation.
