v1.3.1

CryptoLabs Proxy 1.3.1 corrects the shared self-hosted runner temporary-directory collision that stopped the 1.3.0 Python build before publication. Build and publish jobs now allocate separate temporary directories, preserve the original retained artifact bundle for recovery, and retain verified publication receipts after a later reporting failure.

Validation: 46 focused workflow/publication tests passed; independent adversarial checks covered concurrent jobs, stale state, allocation failures, retained-bundle recovery and receipt retention. Application behavior is unchanged from 1.3.0.

Packages and images will be verified through the normal release workflows before standard-customer deployment validation. Suite compatibility, fresh customer installation and both dogfood deployments remain under verification; deployment aliases and GitHub Latest will be promoted after those checks.
