Summary
Request to add USD1 to the core assets configuration file (projects/helper/coreAssets.json) to support the growing adoption of USD1 across various DeFi protocols and launchpads.

Background
USD1 is seeing increasingly widespread adoption across the DeFi ecosystem, particularly in launchpads and other DeFi platforms that are integrating USD1 as a primary stablecoin option. Many projects are now launching with USD1 trading pairs, and having USD1 included in the core assets configuration would enable these protocols to properly track their TVL using DeFiLlama adapters.

Current State
Currently, coreAssets.json includes major stablecoins like USDC, USDT, DAI, BUSD, etc., but USD1 is missing from the configuration. This means protocols that use USD1 cannot easily reference it in their adapters using the standard ADDRESSES.{chain}.USD1 pattern.

Proposed Change
Add USD1 token addresses to both Ethereum and BSC chain configurations in projects/helper/coreAssets.json:

"ethereum": {
// ... existing tokens
  "USD1": "0x8d0d000ee44948fc98c9b98a4fa4921476f08b0d"
},
"bsc": {
  // ... existing tokens
  "USD1": "0x8d0d000ee44948fc98c9b98a4fa4921476f08b0d"
}
