Broadcast and multiply into a fully overwritten uninitialized output.

Axis mappings, shapes, destination injectivity, and reachable-byte overlap are validated before the first write. Safe Rust borrows already prevent input/output aliasing; the explicit overlap check preserves the contract for views produced through unsafe constructors.

Ok(()) means every logical destination element is initialized. An error occurs before writes. A panic during replay may leave a partially initialized destination, which remains safe to drop as MaybeUninit<D>.

Errors

Returns a typed rank, axis, or shape error for an invalid broadcast mapping, StridedError::NonInjectiveOutputLayout for an overlapping output layout, StridedError::OverlappingInputOutput for aliased storage, or StridedError::OffsetOverflow when a reachable byte range is not representable.
