Performance rules

• Avoid clone(), to_vec(), collect() (including implicit collects) on hot paths unless unavoidable. Prefer: borrowing, iter_mut, chunks_exact(_mut), split_at_mut, SmallVec, preallocation with with_capacity, extend_from_slice, and iterator fusion.
• Avoid repeated full passes over large vectors: combine passes; compute multiple derived arrays in one traversal.
• Prefer par_iter / into_par_iter for large independent work: only if thread-safe + no ordering side effects.
• Avoid extra buffering between stages unless it reduces comms or enables parallelism.
