- Fix rebrand issues in pezkuwi-subxt signer (sp_core -> pezsp_core, sp_keyring -> pezsp_keyring, sp_runtime -> pezsp_runtime) - Fix pezkuwi-zombienet-sdk tests (subxt::PolkadotConfig -> pezkuwi_subxt::PezkuwiConfig) - Correct artifact paths in subxt examples (polkadot_metadata_*.scale) - Fix type conversion issues in subxt examples (explicit constructors instead of .into() for generated types) - Add pezkuwi-subxt-utils-stripmetadata dev-dependency to metadata crate - Use original polkadot module from external frame-decode crate - Fix Display trait usage for generated AccountId32 types
