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.

+# System Module
+
+The System module provides low-level access to core types and cross-cutting utilities. It acts as the base layer for
+other pallets to interact with the Bizinikiwi framework components.
+
+- [`system::Config`](https://docs.rs/pezframe-system/latest/frame_system/pallet/trait.Config.html)
+
+## Overview
+
+The System module defines the core data types used in a Bizinikiwi runtime. It also provides several utility functions
+(see [`Pallet`](https://docs.rs/pezframe-system/latest/frame_system/pallet/struct.Pallet.html)) for other FRAME pallets.
+
+In addition, it manages the storage items for extrinsics data, indexes, event records, and digest items, among other
+things that support the execution of the current block.
+
+It also handles low-level tasks like depositing logs, basic set up and take down of temporary storage entries, and
+access to previous block hashes.
+
+## Interface
+
+### Dispatchable Functions
+
+The System module does not implement any dispatchable functions.
+
+### Public Functions
+
+See the [`Pallet`](https://docs.rs/pezframe-system/latest/frame_system/pallet/struct.Pallet.html) struct for details of
+publicly available functions.
+
+### Signed Extensions
+
+The System module defines the following extensions:
+
+  - [`CheckWeight`]: Checks the weight and length of the block and ensure that it does not exceed the limits.
+  - [`CheckNonce`]: Checks the nonce of the transaction. Contains a single payload of type `T::Nonce`.
+  - [`CheckEra`]: Checks the era of the transaction. Contains a single payload of type `Era`.
+  - [`CheckGenesis`]: Checks the provided genesis hash of the transaction. Must be a part of the signed payload of the
+    transaction.
+  - [`CheckSpecVersion`]: Checks that the runtime version is the same as the one used to sign the transaction.
+  - [`CheckTxVersion`]: Checks that the transaction version is the same as the one used to sign the transaction.
+
+Lookup the runtime aggregator file (e.g. `node/runtime`) to see the full list of signed extensions included in a chain.
+
+## Usage
+
+### Prerequisites
+
+Import the System module and derive your module's configuration trait from the system trait.
+
+### Example - Get extrinsic count and parent hash for the current block
+
+```rust
+#[frame_support::pallet]
+pub mod pallet {
+    use super::*;
+    use frame_support::pallet_prelude::*;
+    use frame_system::pallet_prelude::*;
+
+    #[pallet::config]
+    pub trait Config: frame_system::Config {}
+
+    #[pallet::pallet]
+    pub struct Pallet<T>(_);
+
+    #[pallet::call]
+    impl<T: Config> Pallet<T> {
+        #[pallet::weight(0)]
+        pub fn system_module_example(origin: OriginFor<T>) -> DispatchResult {
+            let _sender = ensure_signed(origin)?;
+            let _extrinsic_count = <system::Pallet<T>>::extrinsic_count();
+            let _parent_hash = <system::Pallet<T>>::parent_hash();
+            Ok(())
+        }
+    }
+}
+```
