This commit systematically rebrands various references from Parity Technologies' Polkadot/Substrate ecosystem to PezkuwiChain within the kurdistan-sdk. Key changes include: - Updated external repository URLs (zombienet-sdk, parity-db, parity-scale-codec, wasm-instrument) to point to pezkuwichain forks. - Modified internal documentation and code comments to reflect PezkuwiChain naming and structure. - Replaced direct references to with or specific paths within the for XCM, Pezkuwi, and other modules. - Cleaned up deprecated issue and PR references in various and files, particularly in and modules. - Adjusted image and logo URLs in documentation to point to PezkuwiChain assets. - Removed or rephrased comments related to external Polkadot/Substrate PRs and issues. This is a significant step towards fully customizing the SDK for the PezkuwiChain ecosystem.
