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.

+
+## Overview
+
+The Oracle pallet provides a decentralized and trustworthy way to bring external, off-chain data onto the
+blockchain. It allows a configurable set of oracle operators to feed data, such as prices, into the system.
+This data can then be used by other pallets.
+
+The pallet is designed to be flexible and can be configured to use different data sources and aggregation
+strategies.
+
+## Key Concepts
+
+- **Oracle Operators**: A set of trusted accounts that are authorized to submit data to the oracle. The pallet
+  uses the `frame_support::traits::SortedMembers` trait to manage the set of operators. This allows using pallets
+  like `pezpallet-membership` to manage the oracle members.
+- **Data Feeds**: Operators feed data as key-value pairs. The `OracleKey` is used to identify the data being fed
+  (e.g., a specific currency pair), and the `OracleValue` is the data itself (e.g., the price).
+- **Data Aggregation**: The pallet can be configured with a `CombineData` implementation to aggregate the raw
+  values submitted by individual operators into a single, trusted value. A default implementation
+  `DefaultCombineData` is provided, which takes the median of the values.
+- **Timestamped Data**: All data submitted to the oracle is timestamped, allowing consumers of the data to know
+  how fresh it is.
+
+## Interface
+
+### Dispatchable Functions
+
+- `feed_values` - Allows an authorized oracle operator to submit a set of key-value data points.
+
+### Public Functions
+
+- `get` - Returns the aggregated and timestamped value for a given key.
+- `get_all_values` - Returns all aggregated and timestamped values.
+- `read_raw_values` - Returns the raw, un-aggregated values for a given key from all oracle operators.
+
+### Data Providers
+
+The pallet implements the `DataProvider` and `DataProviderExtended` traits, allowing other pallets to easily
+consume the oracle data.
+
+## Usage
+
+To use the oracle pallet, you need to:
+
+1. **Add it to your runtime's `Cargo.toml`**.
+2. **Implement the `Config` trait** for the pallet in your runtime. This includes specifying:
+   - `OnNewData`: A hook to perform actions when new data is received.
+   - `CombineData`: The data aggregation strategy.
+   - `Time`: The time provider.
+   - `OracleKey`, `OracleValue`: The types for the data key and value.
+   - `RootOperatorAccountId`: An account with sudo-like permissions for the oracle.
+   - `Members`: The source of oracle operators.
+3. **Add the pallet to your runtime's `construct_runtime!` macro**.
+
+Once configured, authorized operators can call `feed_values` to submit data, and other pallets can use the
+`DataProvider` trait to read the aggregated data.
