feat: Rebrand Polkadot/Substrate references to PezkuwiChain
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.

//! This crate offers elliptic curves types which are compatible with the
|

//! [Arkworks](https://github.com/arkworks-rs) library functionalities.
|
||||
//!
|
||||
//! The implementation has been primarily designed to be used in slow hosted
|
||||
//! targets (e.g. wasm32) and offloads the most computationally expensive
|
||||
//! operations to the host by leveraging the
|
||||
//! [arkworks-extensions](https://github.com/paritytech/arkworks-extensions)
|
||||
//! library and Bizinikiwi's host functions.
|
||||
//!
|
||||
//! The exported types are organized and named in a way that mirrors the structure
|
||||
//! of the types in the original Arkworks library. This design choice aims to make
|
||||
//! it easier for users already familiar with the library to understand and utilize
|
||||
//! the exported types effectively.
