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.

+# Timestamp Module
+
+The Timestamp module provides functionality to get and set the on-chain time.
+
+- [`timestamp::Config`](https://docs.rs/pezpallet-timestamp/latest/pallet_timestamp/pallet/trait.Config.html)
+- [`Call`](https://docs.rs/pezpallet-timestamp/latest/pallet_timestamp/pallet/enum.Call.html)
+- [`Pallet`](https://docs.rs/pezpallet-timestamp/latest/pallet_timestamp/pallet/struct.Pallet.html)
+
+## Overview
+
+The Timestamp module allows the validators to set and validate a timestamp with each block.
+
+It uses inherents for timestamp data, which is provided by the block author and validated/verified
+by other validators. The timestamp can be set only once per block and must be set each block.
+There could be a constraint on how much time must pass before setting the new timestamp.
+
+**NOTE:** The Timestamp module is the recommended way to query the on-chain time instead of using
+an approach based on block numbers. The block number based time measurement can cause issues
+because of cumulative calculation errors and hence should be avoided.
+
+## Interface
+
+### Dispatchable Functions
+
+- `set` - Sets the current time.
+
+### Public functions
+
+- `get` - Gets the current time for the current block. If this function is called prior to
+setting the timestamp, it will return the timestamp of the previous block.
+
+### Config Getters
+
+- `MinimumPeriod` - Gets the minimum (and advised) period between blocks for the chain.
+
+## Usage
+
+The following example shows how to use the Timestamp module in your custom module to query the current timestamp.
+
+### Prerequisites
+
+Import the Timestamp module into your custom module and derive the module configuration
+trait from the timestamp trait.
+
+### Get current timestamp
+
+```rust
+use pallet_timestamp::{self as timestamp};
+
+#[frame_support::pallet]
+pub mod pallet {
+    use super::*;
+    use frame_support::pallet_prelude::*;
+    use frame_system::pallet_prelude::*;
+
+    #[pallet::pallet]
+    pub struct Pallet<T>(_);
+
+    #[pallet::config]
+    pub trait Config: frame_system::Config + timestamp::Config {}
+
+    #[pallet::call]
+    impl<T: Config> Pallet<T> {
+        #[pallet::weight(0)]
+        pub fn get_time(origin: OriginFor<T>) -> DispatchResult {
+            let _sender = ensure_signed(origin)?;
+            let _now = <timestamp::Pallet<T>>::get();
+            Ok(())
+        }
+    }
+}
+```
+
+### Example from the FRAME
+
+The [Session module](https://github.com/pezkuwichain/pezkuwi-sdk/blob/master/bizinikiwi/pezframe/session/src/lib.rs) uses
+the Timestamp module for session management.
