- Archived multiple non-EVM adapters (Algorand, Hedera, Tron, TON, Cosmos, Solana) and compliance contracts (IndyVerifier) to `archive/solidity/contracts/`. - Updated documentation to reflect the historical status of archived components. - Adjusted `foundry.toml` and `README.md` for clarity on historical dependencies and configurations. - Enhanced Makefile and package.json scripts for improved contract testing and building processes. - Removed obsolete contracts (AlltraCustomBridge, CommodityCCIPBridge, ISO4217WCCIPBridge, VaultBridgeAdapter) from the main directory. - Updated implementation reports to indicate archived status for various components.
