docs(releases): add release doc for ampd v1.12.0

[eguajardo]

Greptile Summary

Updated On: 2025-09-19 20:21:32 UTC

This PR adds a new release documentation file for ampd v1.12.0, following the established template pattern used throughout the Axelar contract deployments repository. The release specifically addresses account sequence management issues during high concurrency scenarios.

The document follows the standard structure seen in other release files in the /releases/ampd/ directory, including owner information, deployment status tracking across environments (Devnet Amplifier, Stagenet, Testnet, Mainnet), background context, and deployment instructions. This fits into the broader ecosystem of release documentation that provides centralized tracking and guidance for all Axelar component deployments.

The key technical aspect of this release is the introduction of new configuration parameters in the event_processor and broadcast sections: tx_broadcast_buffer_size, tx_confirmation_buffer_size, and tx_confirmation_queue_cap. These parameters allow operators to tune buffer sizes and queue capacity to optimize throughput and resource usage based on their specific deployment requirements.

The documentation includes proper version verification commands and maintains the established format for deployment tracking across different network environments, ensuring consistency with other ampd release documentation in the repository.
