feat: add new ContractOutputType values for structured findings

  Add 13 new enum values (Credentials, Username, Share, AdminUsername,
  Group, Computer, PasswordPolicy, Delegation, Sid, Vulnerability,
  AccountWithPasswordNotRequired, AsreproastableAccount,
  KerberoastableAccount) to support domain-specific finding extraction.

  Closes #191
