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.

+# Keys and Security
+
+The following information is not exhaustive but meant to prevent the most common mistakes. You can read more about
+security and risks in the [Pezkuwi Wiki](https://wiki.network.pezkuwichain.io/docs/learn-account-generation). The Pezkuwi
+network has a few **test networks**, e.g. **Zagros**. Test networks are a great way to experiment and learn safely as
+you can lose tokens on those networks without any financial consequences.
+
+`subkey` generates and provides 2 pieces of **secret** information:
+- **secret phrase**: a bunch of words, exactly 12 by default (can be 12, 15, 18, 21 or 24)
+- **secret seed**: a big hexadecimal value
+
+There are 2 risks related to private keys:
+- loss of keys: this can happen if you don't have a proper backup
+- leak of the keys: this can unfortunately happen in many ways, including malware, phishing, key logger, backups on
+  system that are online and not properly secured
+
+You want to ensure that:
+- you **do not lose** those secrets
+- **no one but you can access** those secrets
+
+☠️ **DO NOT SHARE** your mnemonic phrase or secret seed with ANYONE under **ANY** circumstances. Doing so would give
+them access to your funds and to send transactions on your behalf.
+
+☠️ If someone is asking for your **secret** phrase or **secret** seed, you can be **SURE** they are attempting to steal
+your funds.
+
+✅ It is however fine to share your **SS58 Address** as this is meant to be public information and is needed by anyone
+you want to be able to make transfer to or otherwise interact with your account. They will only ever need your **Public
+Address**.
+
+⚠️ While using the same key on multiple networks is possible, it is usually **not** recommended unless you have good
+motivations for doing so and understand the associated risks and drawbacks.
