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(())
+        }
+    }
+}
+```

+/// |NOM|                |NOM|
+///  ||\_ Mandatory
+///  |\__ Operational
+///  \___ Normal
+/// ```
+///
+/// The remaining capacity can be used to dispatch extrinsics. Note that each dispatch class
+/// is being tracked separately, but the sum can't exceed `max_block` (except for `reserved`).
+/// Below you can see a picture representing full block with 3 extrinsics (two `Operational` and
+/// one `Normal`). Each class has it's own limit `max_total`, but also the sum cannot exceed
+/// `max_block` value.
+///
+/// ```text,ignore
+///                          -- `Mandatory` limit (unlimited)
+/// | # |                 |   |

+/// |#  | `Ext2`          |-  - `Normal` limit
+/// | # | `Ext1`          | # |
+/// |  #| `on_initialize` | ##|
+/// |  #| `base_block`    |###|
+/// |NOM|                 |NOM|
+/// ```
+///
+/// It should be obvious now that it's possible for one class to reach it's limit (say `Normal`),
+/// while the block has still capacity to process more transactions (`max_block` not reached,
+/// `Operational` transactions can still go in). Setting `max_total` to `None` disables the
+/// per-class limit. This is generally highly recommended for `Mandatory` dispatch class, while it
+/// can be dangerous for `Normal` class and should only be done with extra care and consideration.
+///
+/// Often it's desirable for some class of transactions to be added to the block despite it being
+/// full. For instance one might want to prevent high-priority `Normal` transactions from pushing
+/// out lower-priority `Operational` transactions. In such cases you might add a `reserved` capacity
+/// for given class.
+///
+/// ```test,ignore
+///              _
+///   #           \
+///   #   `Ext8`   - `reserved`
+///   #          _/
+/// | # | `Ext7                 | - - `Operational` limit
+/// |#  | `Ext6`                |   |
+/// |#  | `Ext5`                |-# - `Normal` limit

+/// if there wasn't the extra `reserved` space for `Operational` transactions. Note that `max_total`
+/// limit applies to `reserved` space as well (i.e. the sum of weights of `Ext7` & `Ext8` mustn't
+/// exceed it). Setting `reserved` to `None` allows the extrinsics to always get into the block up
+/// to their `max_total` limit. If `max_total` is set to `None` as well, all extrinsics witch
+/// dispatchables of given class will always end up in the block (recommended for `Mandatory`

+//! Module helpers for off-chain calls.
+//!
+//! ## Overview
+//!
+//! This module provides transaction related helpers to:
+//! - Submit a raw unsigned transaction
+//! - Submit an unsigned transaction with a signed payload
+//! - Submit a signed transaction.
+//!
+//! ## Usage
+//!
+//! Please refer to [`example-offchain-worker`](../../pezpallet_example_offchain_worker/index.html) for
+//! a concrete example usage of this crate.
+//!
+//! ### Submit a raw unsigned transaction
+//!
+//! To submit a raw unsigned transaction, [`SubmitTransaction`](./struct.SubmitTransaction.html)
+//! can be used.
+//!
+//! ### Signing transactions
+//!
+//! To be able to use signing, the following trait should be implemented:
+//!
+//! - [`AppCrypto`](./trait.AppCrypto.html): where an application-specific key is defined and can be
+//!   used by this module's helpers for signing.
+//! - [`CreateSignedTransaction`](./trait.CreateSignedTransaction.html): where the manner in which
+//!   the transaction is constructed is defined.
+//!
+//! #### Submit an unsigned transaction with a signed payload
+//!
+//! Initially, a payload instance that implements the `SignedPayload` trait should be defined.
+//! See [`PricePayload`](../../pezpallet_example_offchain_worker/struct.PricePayload.html)
+//!
+//! The payload type that is defined defined can then be signed and submitted onchain.
+//!
+//! #### Submit a signed transaction
+//!
+//! [`Signer`](./struct.Signer.html) can be used to sign/verify payloads
