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.

+# Transaction Storage Pallet
+
+Indexes transactions and manages storage proofs.
+
+Allows storing arbitrary data on the chain. Data is automatically removed after `StoragePeriod` blocks, unless the
+storage is renewed. Validators must submit proof of storing a random chunk of data for block `N - StoragePeriod` when
+producing block `N`.
+
+# Running a chain
+
+The following describes how to set up a new storage chain.
+
+Start with generating a chain spec.
+
+```bash
+cargo run --release -- build-spec --chain=local > sc_init.json
+```
+
+Edit the json chain spec file to customise the chain. The storage chain genesis params are configured in the
+`transactionStorage` section. Note that `storagePeriod` is specified in blocks and changing it also requires code
+changes at the moment.
+
+Build a raw spec from the init spec.
+
+```bash
+cargo run --release build-spec --chain=sc_init.json --raw > sc.json
+```
+
+Run a few validator nodes.
+
+```bash
+cargo run --release -- --chain=sc.json -d /tmp/alice --storage-chain --keep-blocks=100800 --ipfs-server --validator --alice
+cargo run --release -- --chain=sc.json -d /tmp/bob --storage-chain --keep-blocks=100800 --ipfs-server --validator --bob
+```
+
+`--storage-chain` enables transaction indexing. `--keep-blocks=100800` enables block pruning. The value here should be
+greater or equal than the storage period. `--ipfs-server` enables serving stored content over IPFS.
+
+Once the network is started, any other joining nodes need to sync with `--sync=fast`. Regular sync will fail because
+block pruning removes old blocks. The chain does not keep full block history.
+
+```bash
+cargo run --release -- --chain=sc.json -d /tmp/charlie --storage-chain --keep-blocks=100800 --ipfs-server --validator --charlie --sync=fast
+```
+
+# Making transactions
+
+To store data use the `transactionStorage.store` extrinsic. And IPFS CID can be generated from the Blake2-256 hash of
+the data.
+
+```js
+const util_crypto = require('@pezkuwi/util-crypto');
+const keyring_api = require('@pezkuwi/keyring');
+const pezkuwi_api = require('@pezkuwi/api');
+const fs = require('fs');
+const multihash = require('multihashes');
+const CID = require('cids')
+
+const wsProvider = new pezkuwi_api.WsProvider();
+const api = await pezkuwi_api.ApiPromise.create({ provider: wsProvider });
+
+const keyring = new keyring_api.Keyring({ type: "sr25519" });
+const alice = keyring.addFromUri("//Alice");
+
+const file = fs.readFileSync('cute_kitten.jpeg');
+const hash = util_crypto.blake2AsU8a(file)
+const encoded_hash = multihash.encode(hash, 'blake2b-256');
+
+const cid = new CID(1, 'blake2b-256', encoded_hash)
+console.log(cid.toString());
+
+const txHash = await api.tx.transactionStorage.store('0x' + file.toString('hex')).signAndSend(alice);
+```
+Data can be queried over IPFS
+
+```bash
+ipfs swarm connect <bizinikiwi peer address>
+ipfs block get /ipfs/<CID> > kitten.jpeg
+```
+
+To renew data and prevent it from being disposed after the storage period, use `transactionStorage.renew(block, index)`
+where `block` is the block number of the previous store or renew transaction, and index is the index of that transaction
+in the block.
