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.

+//! # Utility Pallet
+//! A stateless pallet with helpers for dispatch management which does no re-authentication.
+//!
+//! - [`Config`]
+//! - [`Call`]
+//!
+//! ## Overview
+//!
+//! This pallet contains two basic pieces of functionality:
+//! - Batch dispatch: A stateless operation, allowing any origin to execute multiple calls in a
+//!   single dispatch. This can be useful to amalgamate proposals, combining `set_code` with
+//!   corresponding `set_storage`s, for efficient multiple payouts with just a single signature
+//!   verify, or in combination with one of the other two dispatch functionality.
+//! - Pseudonymal dispatch: A stateless operation, allowing a signed origin to execute a call from
+//!   an alternative signed origin. Each account has 2 * 2**16 possible "pseudonyms" (alternative
+//!   account IDs) and these can be stacked. This can be useful as a key management tool, where you
+//!   need multiple distinct accounts (e.g. as controllers for many staking accounts), but where
+//!   it's perfectly fine to have each of them controlled by the same underlying keypair. Derivative
+//!   accounts are, for the purposes of proxy filtering considered exactly the same as the origin
+//!   and are thus hampered with the origin's filters.
+//!
+//! Since proxy filters are respected in all dispatches of this pallet, it should never need to be
+//! filtered by any proxy.
+//!
+//! ## Interface
+//!
+//! ### Dispatchable Functions
+//!
+//! #### For batch dispatch
+//! * `batch` - Dispatch multiple calls from the sender's origin.
+//!
+//! #### For pseudonymal dispatch
+//! * `as_derivative` - Dispatch a call from a derivative signed origin.
+
+// Ensure we're `no_std` when compiling for Wasm.
