feat: add PermissionedDomains support (XLS-80)#157
Draft
Conversation
…r XLS-80 Add the Credential serde_with_tag type for wrapping issuer/credential_type pairs, and add PermissionedDomainSet and PermissionedDomainDelete variants to the TransactionType enum. Module declarations for the new transaction types are included.
Implement the PermissionedDomainSet transaction for creating and updating permissioned domains. Supports optional DomainID for updates, a list of accepted Credential entries, and the full CommonTransactionBuilder pattern with builder methods for domain-specific fields.
Implement the PermissionedDomainDelete transaction for removing an existing permissioned domain from the ledger. Takes a required DomainID field identifying the domain to delete.
Add the PermissionedDomain ledger object representing a permissioned domain on the XRP Ledger, with owner, accepted_credentials, sequence, owner_node, previous_txn_id, and previous_txn_lgr_seq fields. Register as LedgerEntryType 0x0082 and add the LedgerEntry enum variant.
Add integration test stubs for PermissionedDomainSet and PermissionedDomainDelete transactions. These tests verify transaction construction, signing, and submission against a running XRPL node, accepting temDISABLED when the amendment is not yet enabled.

Required Credential fields typed as Option without validation — flagged inline.

The XLS-80 spec requires both `issuer` and `credential_type` on every Credential entry. Having them typed as `Option<String>` allowed callers to construct silently invalid transactions. - Change `Credential.issuer` and `Credential.credential_type` from `Option<String>` to `String`, matching the Signer struct pattern. - Add `get_errors()` validation in `PermissionedDomainSet` that rejects empty issuer or credential_type with `MissingField`. - Add two tests covering the new validation paths. - Update all call sites (unit tests, integration test, ledger object tests) to use non-optional field construction.
