- Replace `.expect("INVARIANT: rate_limit_per_second must be > 0")` with
`.unwrap_or(NonZeroU32::new(100).expect("100 > 0"))` — falls back to 100 rps
when config value is zero instead of panicking
- Replace `.expect("INVARIANT: Semaphore should never be closed")` in batch
processor loop with a match that logs and breaks cleanly on semaphore closure
- Replace `.expect("Failed to clone Mamba2SSM")` in Clone impl with a match
that logs the error and calls `std::process::abort()` — makes the panic
explicit and avoids unwrap_used lint
