Asqav Python distribution

The SDK uses the Elastic License 2.0 terms in LICENSE.
The file-level exception is asqav/verifier/verify_receipt.py
(src/asqav/verifier/verify_receipt.py in the source distribution), whose
header specifies the Apache License 2.0 and retains this notice:

Copyright 2026 Asqav

The Apache terms for that file are in licenses/Apache-2.0.txt. The broader
verifier package and its oracle remain under the SDK's Elastic terms.
The distribution's combined license expression describes these file scopes;
it does not offer a choice of licenses for the SDK.
