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.

+## Identity Pallet
+
+- [`Config`]
+- [`Call`]
+
+### Overview
+
+A federated naming system, allowing for multiple registrars to be added from a specified origin.
+Registrars can set a fee to provide identity-verification service. Anyone can put forth a
+proposed identity for a fixed deposit and ask for review by any number of registrars (paying
+each of their fees). Registrar judgements are given as an `enum`, allowing for sophisticated,
+multi-tier opinions.
+
+Some judgements are identified as *sticky*, which means they cannot be removed except by
+complete removal of the identity, or by the registrar. Judgements are allowed to represent a
+portion of funds that have been reserved for the registrar.
+
+A super-user can remove accounts and in doing so, slash the deposit.
+
+All accounts may also have a limited number of sub-accounts which may be specified by the owner;
+by definition, these have equivalent ownership and each has an individual name.
+
+The number of registrars should be limited, and the deposit made sufficiently large, to ensure
+no state-bloat attack is viable.
+
+#### Usernames
+
+The pallet provides functionality for username authorities to issue usernames, which are independent
+of the identity information functionality; an account can set:
+- an identity without setting a username
+- a username without setting an identity
+- an identity and a username
+
+The username functionality implemented in this pallet is meant to be a user friendly lookup of
+accounts. There are mappings in both directions, "account -> username" and "username -> account".
+
+To grant a username, a username authority can either:
+- be given an allocation by governance of a specific amount of usernames to issue for free,
+  without any deposit associated with storage costs;
+- put up a deposit for each username it issues (usually a subsidized, reduced deposit, relative
+  to other deposits in the system).
+
+Users can have multiple usernames that map to the same `AccountId`, however one `AccountId` can only
+map to a single username, known as the _primary_. This primary username will be the result of a
+lookup in the `UsernameOf` map for any given account.
+
+### Interface
+
+#### Dispatchable Functions
+
+##### For General Users
+- `set_identity` - Set the associated identity of an account; a small deposit is reserved if not
+  already taken.
+- `clear_identity` - Remove an account's associated identity; the deposit is returned.
+- `request_judgement` - Request a judgement from a registrar, paying a fee.
+- `cancel_request` - Cancel the previous request for a judgement.
+- `accept_username` - Accept a username issued by a username authority.
+- `remove_expired_approval` - Remove a username that was issued but never accepted.
+- `set_primary_username` - Set a given username as an account's primary.
+- `remove_username` - Remove a username after its grace period has ended.
+
+##### For General Users with Sub-Identities
+- `set_subs` - Set the sub-accounts of an identity.
+- `add_sub` - Add a sub-identity to an identity.
+- `remove_sub` - Remove a sub-identity of an identity.
+- `rename_sub` - Rename a sub-identity of an identity.
+- `quit_sub` - Remove a sub-identity of an identity (called by the sub-identity).
+
+##### For Registrars
+- `set_fee` - Set the fee required to be paid for a judgement to be given by the registrar.
+- `set_fields` - Set the fields that a registrar cares about in their judgements.
+- `provide_judgement` - Provide a judgement to an identity.
+
+##### For Username Authorities
+- `set_username_for` - Set a username for a given account. The account must approve it.
+- `unbind_username` - Start the grace period for a username.
+
+##### For Superusers
+- `add_registrar` - Add a new registrar to the system.
+- `kill_identity` - Forcibly remove the associated identity; the deposit is lost.
+- `add_username_authority` - Add an account with the ability to issue usernames.
+- `remove_username_authority` - Remove an account with the ability to issue usernames.
+- `kill_username` - Forcibly remove a username.
