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.

+# DO NOT USE IN PRODUCTION
+
+The produced values do not fulfill the cryptographic requirements for random numbers. Should not be used for high-stake
+production use-cases.
+
+# Randomness Module
+
+The Randomness Collective Flip module provides a
+[`random`](https://docs.rs/pezpallet-insecure-randomness-collective-flip/latest/pallet_insecure_randomness_collective_flip/struct.Module.html#method.random)
+function that generates low-influence random values based on the block hashes from the previous `81` blocks.
+Low-influence randomness can be useful when defending against relatively weak adversaries. Using this pallet as a
+randomness source is advisable primarily in low-security situations like testing.
+
+## Public Functions
+
+See the
+[`Module`](https://docs.rs/pezpallet-insecure-randomness-collective-flip/latest/pallet_insecure_randomness_collective_flip/struct.Module.html)
+struct for details of publicly available functions.
+
+## Usage
+
+### Prerequisites
+
+Import the Randomness Collective Flip module and derive your module's configuration trait from the system trait.
+
+### Example - Get random seed for the current block
+
+```rust
+use frame_support::traits::Randomness;
+
+#[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 + pallet_insecure_randomness_collective_flip::Config {}
+
+    #[pallet::call]
+    impl<T: Config> Pallet<T> {
+        #[pallet::weight(0)]
+        pub fn random_module_example(origin: OriginFor<T>) -> DispatchResult {
+            let _random_value = pallet_insecure_randomness_collective_flip::Pallet::<T>::random(&b"my context"[..]);
+            Ok(())
+        }
+    }
+}
+```
