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 [`CheckMetadataHash`] transaction extension.
//!
//! The extension for optionally checking the metadata hash. For information how it works and what
//! it does exactly, see the docs of [`CheckMetadataHash`].
//!
//! # Integration
//!
//! As any transaction extension you will need to add it to your runtime transaction extensions:
#![doc = docify::embed!("src/tests.rs", add_metadata_hash_extension)]
//! As the extension requires the `RUNTIME_METADATA_HASH` environment variable to be present at
//! compile time, it requires a little bit more setup. To have this environment variable available
//! at compile time required to tell the `bizinikiwi-wasm-builder` to do so:
#![doc = docify::embed!("src/tests.rs", enable_metadata_hash_in_wasm_builder)]
//! As generating the metadata hash requires to compile the runtime twice, it is
//! recommended to only enable the metadata hash generation when doing a build for a release or when
//! you want to test this feature.

/// The metadata hash is cryptographical representation of the runtime metadata. This metadata hash
/// is build as described in [RFC78](https://polkadot-fellows.github.io/RFCs/approved/0078-merkleized-metadata.html).
/// This metadata hash should give users the confidence that what they build with an online wallet
/// is the same they are signing with their offline wallet and then applying on chain. To ensure
/// that the online wallet is not tricking the offline wallet into decoding and showing an incorrect
/// extrinsic, the offline wallet will include the metadata hash into the extension implicit and
/// the runtime will then do the same. If the metadata hash doesn't match, the signature
/// verification will fail and thus, the transaction will be rejected. The RFC contains more details
/// on how it works.
///
/// The extension adds one byte (the `mode`) to the size of the extrinsic. This one byte is
/// controlling if the metadata hash should be added to the implicit or not. Mode `0` means that
/// the metadata hash is not added and thus, `None` is added to the implicit. Mode `1` means that
/// the metadata hash is added and thus, `Some(metadata_hash)` is added to the implicit. Further
/// values of `mode` are reserved for future changes.
///
/// The metadata hash is read from the environment variable `RUNTIME_METADATA_HASH`. This
/// environment variable is for example set by the `bizinikiwi-wasm-builder` when the feature for
/// generating the metadata hash is enabled. If the environment variable is not set and `mode = 1`
/// is passed, the transaction is rejected with [`UnknownTransaction::CannotLookup`].
