feat(cow-shed): support Poller deployment domains

[igorroncevic]

What and why

ComposableCowPoller integrations can now bundle registerFromShed and revokeFromShed calls through CowShedSdk without subclassing it for custom deployments. CowShedSdk accepts custom factory, implementation, proxy-code, and EIP-712 domain settings, including domain version 2.1.0, while preserving its existing version and subclass APIs.

Depends on #966 and cowprotocol/composable-cow#145.

Test

pnpm --filter @cowprotocol/sdk-cow-shed test

Try it

npm install @cowprotocol/sdk-cow-shed

const cowShedSdk = new CowShedSdk(adapter, {
  ...cowShedDeployment,
  domainVersion: '2.1.0',
})
const cowShed = cowShedSdk.getCowShedAccount(chainId, funder)

const callData = poller.encodeRegisterFromShed({ ...schedule, owner: cowShed })
// To revoke instead: poller.encodeRevokeFromShed({ ...schedule, owner: cowShed })

const signedBundle = await cowShedSdk.signCalls({
  chainId,
  signer,
  calls: [{ target: pollerAddress, callData, value: 0n, isDelegateCall: false, allowFailure: false }],
})

The returned bundle targets the configured CowShed factory and signs with EIP-712 domain version 2.1.0.

Installation

These packages require authentication to install from GitHub Packages. First, create a .npmrc file:

# Create .npmrc file in your project root
echo "@cowprotocol:registry=https://npm.pkg.github.com" > .npmrc
echo "//npm.pkg.github.com/:_authToken=YOUR_GITHUB_TOKEN" >> .npmrc

To get your GitHub token:

1. Go to https://github.com/settings/tokens
2. Click "Generate new token (classic)"
3. Check only the "read:packages" scope
4. Copy the token and replace YOUR_GITHUB_TOKEN in the .npmrc file

Then install any of the packages above, either by exact version (i.e. @cowprotocol/cow-sdk@9.2.7-pr-990-1648a2c6.0) or more conveniently by using the tag (@cowprotocol/cow-sdk@pr-990):

# Yarn
yarn add npm:@cowprotocol/cow-sdk@pr-990

# pnpm
pnpm install npm:@cowprotocol/cow-sdk@pr-990

# NPM
npm install npm:@cowprotocol/cow-sdk@pr-990

Update to the latest version (only if you used the tag)

Every commit will publish a new package. To upgrade to the latest version, run:

# Yarn
yarn upgrade @cowprotocol/cow-sdk

# pnpm
pnpm update @cowprotocol/cow-sdk

# NPM
npm update @cowprotocol/cow-sdk

I think packages/cow-shed/src/const.ts also needs to be updated to add 2.1.0, and we probably want to make it the COW_SHED_LATEST_VERSION.
