Cross Chain Token Aggregator - New Template

Adds a new starter template demonstrating a user-centric cross-chain token aggregation pattern using CRE Event workflow

What It Does

• A CRE LogTrigger watches for ERC-20 Transfer events directed at a configured user address. When a matching transfer is detected, the workflow processes the events, and automatically bridges the tokens to the user's desired wallet on a single unichain via preferred Chainlink CCIP or Across Bridge.
• Allows users to manage scattered token receipts and bridge them on a single chain via automated workflow triggered by Transfer event.
• Also informs the user about the token receipt via Telegram bot notification.
