## Summary by CodeRabbit

- **New Features**
- Added ability to generate 32 random bytes through a new utility
function.
- Introduced various test cases to validate transaction execution,
hardforks, block rewards, and address warming in the virtual machine
environment.

- **Enhancements**
	- Improved utility exports with `GWEI_TO_WEI` and `randomBytes`.
	- Updated `validateRunTx` function for better block handling.
- Reorganized and streamlined code structure in block and transaction
handling.

- **Tests**
- Added extensive test coverage for functions like `execHardfork`,
`runTx`, `createBaseVm`, and more.
- Ensured various transaction scenarios and virtual machine state
behaviors are properly validated.

- **Dependencies**
- Added `@tevm/contract` as a new development dependency in the VM
package.
