//! Drives the canonical encode/decode round-trip fuzz harness from the command
//! line, so the 1M-iteration hand-off gate (and larger soak runs) can run
//! outside the unit-test timeout.
//!
//! Usage:
//!   cargo run --release --example fuzz_roundtrip [ITERS] [SEED]
//!
//! Defaults: 1_000_000 iterations, seed 0. Exits non-zero (via panic) on the
//! first round-trip violation.
