Add scenario TOML files covering a broad range of EVM gas patterns and real-world DeFi/infrastructure interactions: - erc721: NFT mint and transfer - erc1155: multi-token mint, transfer, and batch transfer - erc4626vault: vault deposit/withdraw with share accounting - governance: proposal creation and voting - lending: collateral deposit, borrow, and repay - simpleAMM: constant-product swaps with 0.3% fee - stablecoin: ETH-backed mint/burn/flash mint - nameRegistry: ENS-like name registration and renewal - multisig: multi-sig submit/confirm/execute - staking: stake/unstake/claim/compound rewards - precompiles/hashPrecompiles: SHA256, RIPEMD160, Identity stress - bridge: L1→L2 deposit simulation (ETH + ERC20) - dutchAuction: time-based pricing with ETH refunds - orderBook: on-chain limit orders with partial fills Also adds campaigns/full-spectrum.toml: a 4-stage campaign (warmup → DeFi ramp → full load → cooldown) that mixes all new scenarios for comprehensive chain stress testing. All contracts are self-contained Solidity 0.8.26, compiled with solc --optimize --optimize-runs 200. Each scenario includes deploy, setup (liquidity/approvals/funding), and fuzzed spam.

Research-driven wave 2: analyzed top gas consumers, block composition, and novel EVM patterns on Ethereum mainnet to identify the highest- impact scenarios missing from contender. New scenarios: - erc4337: Account Abstraction EntryPoint with two-loop validate→execute pattern, deposit accounting, UserOp helper - flashLoan: ERC-3156 flash loan with 5-level deep arbitrage callback (lender→borrower→poolA→poolB→repay) - bondingCurve: Pump.fun-style token launchpad with linear bonding curve math + CREATE2 factory deployment as spam - merkleAirdrop: keccak256-heavy proof verification with packed claimed bitmap (256 claims per storage slot) - create2Factory: ERC-1167 minimal proxy clones via CREATE2 (contract creation as the hot path, not function calls) - multicall3: Batched heterogeneous calls (5-50 per tx), testing memory expansion and loop overhead - weth: WETH9 wrap/unwrap — one of highest-volume mainnet contracts, covers payable+msg.value+ERC20 mint pattern - stableSwap: Curve-style StableSwap AMM with Newton's method iteration (up to 255 rounds per swap) — fundamentally different gas profile from constant-product AMMs - mevSandwich: MEV sandwich bundles using [[spam.bundle.tx]] with frontrun→victim→backrun atomic ordering - diamondProxy: EIP-2535 Diamond with delegatecall dispatch routing through CounterFacet, TokenFacet, StorageFacet All contracts self-contained Solidity 0.8.26, compiled with solc --optimize --optimize-runs 200.

Summary
Wave 2 of scenario expansion, informed by analyzing Ethereum mainnet block composition, top gas consumers (Etherscan/Dune), and emerging EVM patterns.
Builds on top of #475 (14 basic scenarios + campaign).
