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.

+# Executive Module
+
+The Executive module acts as the orchestration layer for the runtime. It dispatches incoming extrinsic calls to the
+respective modules in the runtime.
+
+## Overview
+
+The executive module is not a typical pallet providing functionality around a specific feature. It is a cross-cutting
+framework component for the FRAME. It works in conjunction with the [FRAME System
+module](https://docs.rs/pezframe-system/latest/frame_system/) to perform these cross-cutting functions.
+
+The Executive module provides functions to:
+
+- Check transaction validity.
+- Initialize a block.
+- Apply extrinsics.
+- Execute a block.
+- Finalize a block.
+- Start an off-chain worker.
+
+### Implementations
+
+The Executive module provides the following implementations:
+
+- `Executive`: Type that can be used to make the FRAME available from the runtime.
+
+## Usage
+
+The default Bizinikiwi node template declares the
+[`Executive`](https://docs.rs/pezframe-executive/latest/frame_executive/struct.Executive.html) type in its library.
+
+### Example
+
+`Executive` type declaration from the node template.
+
+```rust
+/// Executive: handles dispatch to the various modules.
+pub type Executive = executive::Executive<
+    Runtime,
+    Block,
+    Context,
+    Runtime,
+    AllPalletsWithSystem,
+>;
+```
