5.2

• #5242
• #5243
• #5244
• #5250
• Account framework into openzeppelin-community-contracts

Later

• [ ] #5246
  • should not be packaged, can be removed from files exception
  • need to fix linter
  • alternative, put these files into a dependency that we import
    • that would be cleaner for upgradeability
  • because vendor/erc4337-entrypoint is not package, moving it or removing it would not be breaking
• [ ] When hardhat fixes https://github.com/NomicFoundation/hardhat/issues/4399
  • revert OZ Edit in contracts/vendor/erc4337-entrypoint/core/EntryPoint.sol
  • remove the upgradable.exclude.patch for the transpilation process
