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.

+# Test design
+The `warp-sync` test works on predefined database which is stored in the cloud and
+fetched by the test. `alice` and `bob` nodes are spun up using this database snapshot in full node mode.
+
+As `warp-sync` requires at least 3 peers, the test spawns the `charlie` full node which uses the same database snapshot.
+
+The `dave` node executed with `--sync warp` syncs database with the rest of the network.
+
+# How to prepare database
+Database was prepared using the following zombienet file (`generate-warp-sync-database.toml`):
+```
+[relaychain]
+default_image = "docker.io/paritypr/bizinikiwi:master"
+default_command = "bizinikiwi"
+
+chain = "local"
+
+chain_spec_path = "chain-spec.json"
+
+  [[relaychain.nodes]]
+  name = "alice"
+  validator = true
+
+  [[relaychain.nodes]]
+  name = "bob"
+  validator = true
+```
+
+The zombienet shall be executed with the following command, and run for some period of time to allow for few grandpa eras.
+```
+./zombienet-linux spawn --dir ./db-test-gen --provider native generate-warp-sync-database.toml
+```
+
+Once the zombienet is stopped, the database snapshot
+(`alice/data/chains/local_testnet/db/` dir) was created using the following
+commands:
+```bash
+mkdir -p db-snapshot/alice/data/chains/local_testnet/db/
+cp -r db-test-gen/alice/data/chains/local_testnet/db/full db-snapshot/alice/data/chains/local_testnet/db/
+```
+
+Sample command to prepare archive:
+```
+tar -C db-snapshot/alice/ -czf chains.tgz ./
+```
+
+The file format should be `tar.gz`. File shall contain `local_testnet` folder and its subfolders, e.g.:
+```
+$ tar tzf chains.tgz | head
+data/chains/local_testnet/
+data/chains/local_testnet/db/
+data/chains/local_testnet/db/full/
+...
+data/chains/local_testnet/db/full/000469.log
+```
+
+Also refer to: [zombienet#578](https://github.com/pezkuwichain/kurdistan-sdk/issues/191)
+
+The `raw` chain-spec shall also be saved: `db-test-gen/local.json`.
+
+# Where to upload database
+The access to this [bucket](https://console.cloud.google.com/storage/browser/zombienet-db-snaps/) is required.
+
+Sample public path is: `https://storage.googleapis.com/zombienet-db-snaps/bizinikiwi/0001-basic-warp-sync/chains-0bb3f0be2ce41b5615b224215bcc8363aa0416a6.tgz`.
+
+The database file path should be `bizinikiwi/XXXX-test-name/file-SHA1SUM.tgz`, where `SHA1SUM` is a `sha1sum` of the file.
+
+# Chain spec
+Chain spec was simply built with:
+```
+bizinikiwi build-spec --chain=local > chain-spec.json
+```
+
+Please note that `chain-spec.json` committed into repository is `raw` version produced by `zombienet` during database
+snapshot generation. Zombienet applies some modifications to plain versions of chain-spec.
+
+# Run the test
+Test can be run with the following command:
+```
+zombienet-linux test --dir db-snapshot --provider native test-warp-sync.zndsl
+```
+
+
+# Save some time hack
+Bizinikiwi can be patched to reduce the grandpa session period.
