New Template: Vault Harvester

New Template: Vault Harvester

• Automated DeFi vault harvesting. Same cron → read → check → write pattern as Keeper Bot, but with a yield-based profitability check (shouldHarvest() requires both time interval AND minimum yield threshold).
• Contract tracks pending yield, total harvested, and harvest count.

Could check receiver contract execution status here:

if (
  writeResult.receiverContractExecutionStatus !== undefined &&
  writeResult.receiverContractExecutionStatus !== 0
) {
  throw new Error(`Receiver contract execution failed: status ${writeResult.receiverContractExecutionStatus}`)
}

Could link to this template from the README one level up https://github.com/smartcontractkit/cre-templates/blob/main/starter-templates/README.md?plain=1#L38.

Good suggestion, will do for all templates.
