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.

+//! # Recovery Pallet
+//!
+//! - [`Config`]
+//! - [`Call`]
+//!
+//! ## Overview
+//!
+//! The Recovery pallet is an M-of-N social recovery tool for users to gain
+//! access to their accounts if the private key or other authentication mechanism
+//! is lost. Through this pallet, a user is able to make calls on-behalf-of another
+//! account which they have recovered. The recovery process is protected by trusted
+//! "friends" whom the original account owner chooses. A threshold (M) out of N
+//! friends are needed to give another account access to the recoverable account.
+//!
+//! ### Recovery Configuration
+//!
+//! The recovery process for each recoverable account can be configured by the account owner.
+//! They are able to choose:
+//! * `friends` - The list of friends that the account owner trusts to protect the recovery process
+//!   for their account.
+//! * `threshold` - The number of friends that need to approve a recovery process for the account to
+//!   be successfully recovered.
+//! * `delay_period` - The minimum number of blocks after the beginning of the recovery process that
+//!   need to pass before the account can be successfully recovered.
+//!
+//! There is a configurable deposit that all users need to pay to create a recovery
+//! configuration. This deposit is composed of a base deposit plus a multiplier for
+//! the number of friends chosen. This deposit is returned in full when the account
+//! owner removes their recovery configuration.
+//!
+//! ### Recovery Life Cycle
+//!
+//! The intended life cycle of a successful recovery takes the following steps:
+//! 1. The account owner calls `create_recovery` to set up a recovery configuration for their
+//!    account.
+//! 2. At some later time, the account owner loses access to their account and wants to recover it.
+//!    Likely, they will need to create a new account and fund it with enough balance to support the
+//!    transaction fees and the deposit for the recovery process.
+//! 3. Using this new account, they call `initiate_recovery`.
+//! 4. Then the account owner would contact their configured friends to vouch for the recovery
+//!    attempt. The account owner would provide their old account id and the new account id, and
+//!    friends would call `vouch_recovery` with those parameters.
+//! 5. Once a threshold number of friends have vouched for the recovery attempt, the account owner
+//!    needs to wait until the delay period has passed, starting when they initiated the recovery
+//!    process.
+//! 6. Now the account owner is able to call `claim_recovery`, which subsequently allows them to
+//!    call `as_recovered` and directly make calls on-behalf-of the lost account.
+//! 7. Using the now recovered account, the account owner can call `close_recovery` on the recovery
+//!    process they opened, reclaiming the recovery deposit they placed.
+//! 8. Then the account owner should then call `remove_recovery` to remove the recovery
+//!    configuration on the recovered account and reclaim the recovery configuration deposit they
+//!    placed.
+//! 9. Using `as_recovered`, the account owner is able to call any other pallets to clean up their
+//!    state and reclaim any reserved or locked funds. They can then transfer all funds from the
+//!    recovered account to the new account.
+//! 10. When the recovered account becomes reaped (i.e. its free and reserved balance drops to
+//!     zero), the final recovery link is removed.
+//!
+//! ### Malicious Recovery Attempts
+//!
+//! Initializing the recovery process for a recoverable account is open and
+//! permissionless. However, the recovery deposit is an economic deterrent that
+//! should disincentivize would-be attackers from trying to maliciously recover
+//! accounts.
+//!
+//! The recovery deposit can always be claimed by the account which is trying
+//! to be recovered. In the case of a malicious recovery attempt, the account
+//! owner who still has access to their account can claim the deposit and
+//! essentially punish the malicious user.
+//!
+//! Furthermore, the malicious recovery attempt can only be successful if the
+//! attacker is also able to get enough friends to vouch for the recovery attempt.
+//! In the case where the account owner prevents a malicious recovery process,
+//! this pallet makes it near-zero cost to re-configure the recovery settings and
+//! remove/replace friends who are acting inappropriately.
+//!
+//! ### Safety Considerations
+//!
+//! It is important to note that this is a powerful pallet that can compromise the
+//! security of an account if used incorrectly. Some recommended practices for users
+//! of this pallet are:
+//!
+//! * Configure a significant `delay_period` for your recovery process: As long as you have access
+//!   to your recoverable account, you need only check the blockchain once every `delay_period`
+//!   blocks to ensure that no recovery attempt is successful against your account. Using off-chain
+//!   notification systems can help with this, but ultimately, setting a large `delay_period` means
+//!   that even the most skilled attacker will need to wait this long before they can access your
+//!   account.
+//! * Use a high threshold of approvals: Setting a value of 1 for the threshold means that any of
+//!   your friends would be able to recover your account. They would simply need to start a recovery
+//!   process and approve their own process. Similarly, a threshold of 2 would mean that any 2
+//!   friends could work together to gain access to your account. The only way to prevent against
+//!   these kinds of attacks is to choose a high threshold of approvals and select from a diverse
+//!   friend group that would not be able to reasonably coordinate with one another.
+//! * Reset your configuration over time: Since the entire deposit of creating a recovery
+//!   configuration is returned to the user, the only cost of updating your recovery configuration
+//!   is the transaction fees for the calls. Thus, it is strongly encouraged to regularly update
+//!   your recovery configuration as your life changes and your relationship with new and existing
+//!   friends change as well.
+//!
+//! ## Interface
+//!
+//! ### Dispatchable Functions
+//!
+//! #### For General Users
+//!
+//! * `create_recovery` - Create a recovery configuration for your account and make it recoverable.
+//! * `initiate_recovery` - Start the recovery process for a recoverable account.
+//!
+//! #### For Friends of a Recoverable Account
+//! * `vouch_recovery` - As a `friend` of a recoverable account, vouch for a recovery attempt on the
+//!   account.
+//!
+//! #### For a User Who Successfully Recovered an Account
+//!
+//! * `claim_recovery` - Claim access to the account that you have successfully completed the
+//!   recovery process for.
+//! * `as_recovered` - Send a transaction as an account that you have recovered. See other functions
+//!   below.
+//!
+//! #### For the Recoverable Account
+//!
+//! * `close_recovery` - Close an active recovery process for your account and reclaim the recovery
+//!   deposit.
+//! * `remove_recovery` - Remove the recovery configuration from the account, making it
+//!   un-recoverable.
+//!
+//! #### For Super Users
+//!
+//! * `set_recovered` - The ROOT origin is able to skip the recovery process and directly allow one
+//!   account to access another.
+
+// Ensure we're `no_std` when compiling for Wasm.
