✨ Highlights

• Fixed Mithril ledger state imports so Dingo rebuilds live reward stake even when bulk loading removes the deferred staking index.

• Improved Antithesis run handling by pinning moog to a compatible version, queueing runs instead of canceling active polling jobs, validating duration input, waiting for results, and hardening credential handling.

• Updated the publish and Antithesis workflows to use a newer attestation action.

• Updated github.com/dgraph-io/badger/v4 to a newer patch release with correctness and performance fixes.
