Function build_uniform_error

crates/ffi/src/kernel.rs:3016–3020

Build a result array of length `count` where every slot is the same compile-kind error. Used when compile/ingress/thread setup fails before per-constant checking can begin — the error arose before the kernel was consulted, so `Compile` is the honest tag.

(count: usize, msg: &str)
