Moudy 87170b93b0 refactor(cycle_bench): collapse 9 inline run_case calls into Case struct + iterator

- Introduce `struct Case` holding pre-serialized InstructionData,
  with new<I: Serialize>(...) -> Result<Self> constructor and
  fn run(self, prove, exec_iters) -> Result<BenchResult>.
- Replace 9 inline `run_case(...)?` push calls in main() with
  [Case::new(...)?, ...].into_iter().map(|c| c.run(prove, exec_iters))
  .collect::<Result<Vec<_>>>()?.
- Drop now-unused `needless_pass_by_value` and `too_many_arguments`
  from the crate-level #![expect] block.

cycle_bench

Per-program Risc0 cycle counts, prover wall time, PPE composition cost, and verifier wall time for the built-in LEZ programs. Feeds the fee model (G_executor, G_prove, G_verify, S_agg).

Run

# Executor cycles only (fast, ~seconds)
cargo run --release -p cycle_bench

# + real proving per program (slow, ~minutes)
cargo run --release -p cycle_bench --features prove -- --prove

# + PPE composition cases (very slow, ~hour)
cargo run --release -p cycle_bench --features ppe -- --prove --ppe

# + verifier microbench (G_verify): generates one PPE receipt, times verify x1000
cargo run --release -p cycle_bench --features ppe -- --verify --verify-iters 1000

RISC0_DEV_MODE=1 skips proving entirely and is only useful for the executor path. Combine flags freely; output is printed to stdout and written to target/cycle_bench.json for regression diffs.

What you'll see

Per-program executor cycles and segments, plus exec wall time as best / mean ± stdev (n=N).
With --prove: prover total cycles, paging cycles, segments, and wall time.
With --ppe: end-to-end execute_and_prove wall time and S_agg (the borsh-serialized InnerReceipt length) for one auth-transfer-in-PPE case and a chain-caller depth sweep.
With --verify: verify wall time best / mean ± stdev, plus proof_bytes and journal_bytes.
