🛠️ Mason: Add Distributed Database Sharding Architect

[fderuiter]

💡 What: Added a new expert-level prompt distributed_database_sharding_architect.prompt.yaml to the prompts/technical/architecture domain. It defines an advanced architect persona for designing globally distributed, highly-scalable database sharding strategies.
🎯 Why: To fill a functional gap in the architecture prompts repository by providing a specialized tool for designing complex distributed data topologies.
📊 Impact: Expands the utility of the repository for distributed systems engineers and database architects, ensuring they have an expert agent to assist in designing robust, highly scalable data architectures.
