pezkuwichain 1c0e57d984 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.

Interface

Public Functions

is_online - True if the validator sent a heartbeat in the current session.

Usage

use pallet_im_online::{self as im_online};

#[frame_support::pallet]
pub mod pallet {
    use super::*;
    use frame_support::pallet_prelude::*;
    use frame_system::pallet_prelude::*;

    #[pallet::pallet]
    pub struct Pallet<T>(_);

    #[pallet::config]
    pub trait Config: frame_system::Config + im_online::Config {}

    #[pallet::call]
    impl<T: Config> Pallet<T> {
        #[pallet::weight(0)]
        pub fn is_online(origin: OriginFor<T>, authority_index: u32) -> DispatchResult {
            let _sender = ensure_signed(origin)?;
            let _is_online = <im_online::Pallet<T>>::is_online(authority_index);
            Ok(())
        }
    }
}

Dependencies

This module depends on the Session module.
