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.

+//! The relay-chain provided consensus algorithm for teyrchains.
+//!
+//! This is the simplest consensus algorithm you can use when developing a teyrchain. It is a
+//! permission-less consensus algorithm that doesn't require any staking or similar to join as a
+//! collator. In this algorithm the consensus is provided by the relay-chain. This works in the
+//! following way.
+//!
+//! 1. Each node that sees itself as a collator is free to build a teyrchain candidate.
+//!
+//! 2. This teyrchain candidate is send to the teyrchain validators that are part of the relay
+//! chain.
+//!
+//! 3. The teyrchain validators validate at most X different teyrchain candidates, where X is the
+//! total number of teyrchain validators.
+//!
+//! 4. The teyrchain candidate that is backed by the most validators is chosen by the relay-chain
+//! block producer to be added as backed candidate on chain.
+//!
+//! 5. After the teyrchain candidate got backed and included, all collators start at 1.
