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.

+# Changelog
+
+All notable changes and migrations to pezpallet-staking will be documented in this file.
+
+The format is loosely based
+on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/). We maintain a
+single integer version number for staking pallet to keep track of all storage
+migrations.
+
+## [v16]
+
+
+### Added
+
+- New default implementation of `DisablingStrategy` - `UpToLimitWithReEnablingDisablingStrategy`.
+  Same as `UpToLimitDisablingStrategy` except when a limit (1/3 default) is reached. When limit is
+  reached the offender is only disabled if his offence is greater or equal than some other already
+  disabled offender. The smallest possible offender is re-enabled to make space for the new greater
+  offender. A limit should thus always be respected.
+- `DisabledValidators` changed format to include severity of the offence.
+
+## [v15]
+
+### Added
+
+- New trait `DisablingStrategy` which is responsible for making a decision which offenders should be
+  disabled on new offence.
+- Default implementation of `DisablingStrategy` - `UpToLimitDisablingStrategy`. It
+  disables each new offender up to a threshold (1/3 by default). Offenders are not runtime disabled for
+  offences in previous era(s). But they will be low-priority node-side disabled for dispute initiation.
+- `OffendingValidators` storage item is replaced with `DisabledValidators`. The former keeps all
+  offenders and if they are disabled or not. The latter just keeps a list of all offenders as they
+  are disabled by default.
+
+### Deprecated
+
+- `enum DisableStrategy` is no longer needed because disabling is not related to the type of the
+  offence anymore. A decision if a offender is disabled or not is made by a `DisablingStrategy`
+  implementation.
+
+## [v14]
+
+### Added
+
+- New item `ErasStakersPaged` that keeps up to `MaxExposurePageSize`
+  individual nominator exposures by era, validator and page.
+- New item `ErasStakersOverview` complementary to `ErasStakersPaged` which keeps
+  state of own and total stake of the validator across pages.
+- New item `ClaimedRewards` to support paged rewards payout.
+
+### Deprecated
+
+- `ErasStakers` and `ErasStakersClipped` is deprecated, will not be used any longer for the exposures of the new era
+  post v14 and can be removed after 84 eras once all the exposures are stale.
+- Field `claimed_rewards` in item `Ledger` is renamed
+  to `legacy_claimed_rewards` and can be removed after 84 eras.
