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.

+# I'm online Module
+
+If the local node is a validator (i.e. contains an authority key), this module
+gossips a heartbeat transaction with each new session. The heartbeat functions
+as a simple mechanism to signal that the node is online in the current era.
+
+Received heartbeats are tracked for one era and reset with each new era. The
+module exposes two public functions to query if a heartbeat has been received
+in the current era or session.
+
+The heartbeat is a signed transaction, which was signed using the session key
+and includes the recent best block number of the local validators chain as well
+as the `NetworkState`.
+It is submitted as an Unsigned Transaction via off-chain workers.
