Release: Sovereign Chains v0.5.0

Sovereign Chains v0.5.0 is live!

mx-sovereign-sc v0.5.0 is a major step toward production-ready Sovereign chains on MultiversX. It introduces structured, multi-phase deployments, safer cross-chain execution through hash-locked operations, a first-class fee market, and a consolidated approach to token custody and registration.

Together, these changes reduce hidden complexity, improve operational safety, and give developers clearer, more explicit control over how Sovereign systems are deployed and run.
