Advisories for Cargo/Kora-Lib package

When inner CPI instructions use instruction types not recognized by Kora's parser (including Token-2022 extension instructions like ConfidentialTransfer, TransferFeeExtension::WithdrawWithheldTokens, etc.), they are reconstructed as stub instructions with empty accounts and empty data. These stubs fail deserialization during fee payer policy validation and are silently skipped, meaning any fee payer usage within those instructions goes completely unchecked.

When a user pays transaction fees using a Token-2022 token with a TransferFeeConfig extension, Kora's verify_token_payment() credits the full raw transfer amount as the payment value. However, the on-chain SPL Token-2022 program withholds a portion of that amount as a transfer fee, so the paymaster's destination account only receives amount - transfer_fee. This means the paymaster consistently credits more value than it actually receives, resulting in systematic financial loss.
