Struct RawKeyBuilder 

pub struct RawKeyBuilder<const N: usize> { /* private fields */ }

Fixed-capacity stack key builder for RawStorage keys.

This keeps contract samples on a heap-free path while centralizing the small copy_nonoverlapping block that fixed key construction needs. Push methods return false when the requested write would exceed capacity; existing bytes are left unchanged in that case.
