June 2025 performance summary for hashgraph/hedera-cli: Delivered end-to-end Hardhat integration to enable contract deployment and interaction from the Hedera CLI, refined script workflow and variable handling, and embedded Hardhat workflow within the CLI. Simplified environment setup by centralizing credentials/config at the project root and removing the --path option, enabling smoother onboarding. Added topic message retrieval enhancements with sequence-number filters for granular search.
