Add U18 Upgrade Task for RevShare Betanet

Summary

Adds the new 060-U18-rev-share-betanet task for upgrading RevShare Betanet to U18, and renames the existing RevShare setup task from 060 to 061 to establish proper task ordering (U18 upgrade must run before RevShare setup).

Changes

New: 060-U18-rev-share-betanet

• config.toml: Targets revshare-beta-0 (chainId: 420120033) with v600 OPCM and U18 prestates
• addresses.json: Contract addresses for revshare-beta-0 from devnets repo
• README.md: Task documentation with simulation/signing commands
• VALIDATION.md: Safe address (0xf64bc17485f0B4Ea5F06A96514182FC4cB561977), hashes TBD
• .env: Tenderly gas configuration

Renamed: 060-betanet-rev-share → 061-betanet-rev-share

• Updated all path references from 060 to 061
• Fixed fallbackAddressesJsonPath to point to 061-betanet-rev-share/addresses.json
• Added TODO comment noting betanet will be replaced

TODO Before Merging

• Run simulations and verify they pass:

  just simulate-stack sep 060-U18-rev-share-betanet                                                                                                                                                                 
  just simulate-stack sep 061-betanet-rev-share    

• forge test passing
• Update VALIDATION.md files with actual domain/message hashes from simulation output
• Complete stack simulation just simulate-stack sep

Incoming Betanet

A new betanet is being spun up to replace the current revshare-beta-0. When deployed, the following will need updating:

File	Fields to Update
060/config.toml	l2chains (name, chainId), [[opcmUpgrades]] chainId, prestates (if different), stateOverrides address
060/addresses.json	Chain ID key, all contract addresses
061/config.toml	l2chains (name, chainId), portals, ProxyAdminOwner, stateOverrides addresses
061/addresses.json	Chain ID key, all contract addresses
*/VALIDATION.md	Safe addresses, domain/message hashes

Where to get new values

• Chain name/ID & contract addresses: https://github.com/ethereum-optimism/devnets/tree/main/betanets/
• Prestates: https://www.notion.so/oplabs/Betanet-2a9f153ee16280859261e3000d866ee9
• Safe addresses: From deployment or devnets repo

I dont think we need to wait for betanet for the stateOverrides like mentioned in the description, cant we define these now?
