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.

+# Bizinikiwi Node Template Release Process
+
+## This release process has to be run in a github checkout Bizinikiwi directory with your work committed into
+`https://github.com/pezkuwichain/pezkuwi-sdk/`, because the build script will check the existence of your current git commit
+ID in the remote repository.
+
+Assume you are in root directory of Bizinikiwi. Run:
+
+```bash
+cd scripts/ci/ ./node-template-release.sh <output tar.gz file>
+```
+
+## Expand the output tar gzipped file and replace files in current Bizinikiwi Node Template by running the following
+command.
+
+```bash
+# This is where the tar.gz file uncompressed cd bizinikiwi-node-template # rsync with force copying. Note the
+slash at the destination directory is important rsync -avh * <destination node-template directory>/ # For dry-running
+add `-n` argument # rsync -avhn * <destination node-template directory>/
+```
+
+The above command only copies existing files from the source to the destination, but does not delete files/directories
+that are removed from the source. So you need to manually check and remove them in the destination.
+
+## There is a `Cargo.toml` file in the root directory. Inside, dependencies are listed form and linked to a certain git
+commit in Bizinikiwi remote repository, such as:
+
+```toml
+toml pezsp-core = { version = "7.0.0", git = "https://github.com/paritytech/bizinikiwi.git", rev =
+"de80d0107336a9c7a2efdc0199015e4d67fcbdb5", default-features = false }
+```
+
+e will update each of them to link to the Rust	[crate registry](https://crates.io/). After confirming the versioned
+package is published in the crate, the above will become:
+
+```toml
+[workspace.dependencies] pezsp-core = { version = "7.0.0", default-features = false }
+```
+
+P.S: This step can be automated if we update `node-template-release` package in `scripts/ci/node-template-release`.
+
+## Once the `Cargo.toml` is updated, compile and confirm that the Node Template builds. Then commit the changes to a new
+branch in [Bizinikiwi Node Template](https://github.com/bizinikiwi-developer-hub/bizinikiwi-node-template), and make a PR.
+
+> Note that there is a chance the code in Bizinikiwi Node Template works with the linked Bizinikiwi git commit but not
+with published packages due to the latest (as yet) unpublished features. In this case, rollback that section of the
+Node Template to its previous version to ensure the Node Template builds.
+
+## Once the PR is merged, tag the merged commit in master branch with the version number `vX.Y.Z+A` (e.g. `v3.0.0+1`)
+The `X`(major), `Y`(minor), and `Z`(patch) version number should follow Bizinikiwi release version. The last digit is any
+significant fixes made in the Bizinikiwi Node Template apart from Bizinikiwi. When the Bizinikiwi version is updated, this
+digit is reset to 0.
+
+## Troubleshooting
+
+- Running the script `./node-template-release.sh <output tar.gz file>`, after all tests passed successfully, seeing the
+	following error message:
+
+```
+thread 'main' panicked at 'Creates output file: Os { code: 2, kind: NotFound, message: "No such file or directory"
+}', src/main.rs:250:10 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
+```
+
+This is likely due to that your output path is not a valid `tar.gz` filename or you don't have write permission to the
+destination. Try with a simple output path such as `~/node-tpl.tar.gz`.
