feat: Defender Action to update Votemarket epochs for Curve Pool Booster campaigns

[clement-ux]

Summary

Adds automation to keep Votemarket campaign epochs up to date on Arbitrum.

• contracts/tasks/votemarket.js: Core logic that reads all Curve Pool Booster campaign IDs from the CurvePoolBoosterBribesModule on Mainnet, checks the current epoch on the Arbitrum Votemarket contract, and calls updateEpoch for any campaign whose period has not yet been updated.
• contracts/scripts/defender-actions/updateVotemarketEpochs.js: Defender Action entry point. The relayer is on Arbitrum (chain 42161); Mainnet data is read via event.secrets.PROVIDER_URL. dryRun can be controlled via event.request.body.dryRun (defaults to false in production).
• rollup.config.cjs: Added updateVotemarketEpochs to the build.
• tasks/tasks.js: Registered updateVotemarketEpochs hardhat task (dry-run by default).

How it works

1. Fetch pool boosters from CurvePoolBoosterBribesModule (Mainnet)
2. Read campaignId() from each pool booster (skip if 0)
3. Read currentEpoch() from Votemarket (Arbitrum)
4. For each campaign, call getPeriodPerCampaign(campaignId, epoch) — if updated === false, call updateEpoch(campaignId, epoch, "0x")
5. Individual campaign failures are caught and logged without blocking others

Test plan

• Dry-run via hardhat task: ARBITRUM_PROVIDER_URL=... DEBUG=origin:task:votemarket npx hardhat updateVotemarketEpochs --network mainnet
• Deploy Defender Action with Arbitrum relayer and PROVIDER_URL secret set to a Mainnet RPC
• Trigger manually via Defender and confirm epochs are updated on-chain
