LocalUsersModule lists all local user accounts on the system.
Details
On Linux, the module reads /etc/passwd to enumerate user entries. Each UID is then resolved through the standard os/user library to retrieve the full user details.
On Windows, the module calls the Win32 NetUserEnum API (from netapi32.dll) to enumerate local accounts filtered to normal user accounts. Each username is then resolved with os/user.Lookup, and the user's domain is determined by converting the SID via LookupAccountSid.
The collected users are stored in the database with an upsert strategy based on (machine_id, uid).
