Feature request: preview, batch, and execute Gnosis Safe transactions (ape-safe)

Describe the feature you would like

Description:

My favorite tool from the Brownie/Vyper ecosystem is ape-safe. It lets you:

1. Setup some actions (calling various functions, piping data together in Python)
2. Preview the side effects, running those actions via a Brownie mainnet fork
3. Once everything looks good, batch all the actions via MultiSend and send as one transaction for signers to approve

Now that Foundry is adding support for a local node and deploy scripts, it would be useful to have similar functionality out of the box.

Example:

I'm not sure what this looks like practically yet, but it might just be an executable Solidity script (transcribing the ape-safe Python example):

function script() public {
  Safe gnosis = Safe(0xfeb4acf3df3cdea7399794d0869ef76a6efaff52);

  ERC20 public dai = ERC20(0x6B175474E89094C44Da98b954EedeAC495271d0F);
  yVault public vault = yVault(0x19D3364A399d251E894aC732651be8B0E4e85001);

  uint256 amount = dai.balanceOf(address(gnosis));
  dai.approve(vault, amount);
  vault.deposit(amount);

  // Generate preview transaction
  cheats.preview();
  // Batch transaction
  cheats.batch();
  // Broadcast transaction
  cheats.broadcast(address(gnosis));
}

Potential use-cases:

Some potential applications:

• Automating contract setups or common governance actions
• Using like Hardhat tasks, see example in dYdX repo
• Using like optimism's chug-splash as a mass-deployment system
