Build the complete artifact pillar with five packages: - artifacts: Artifact, Snapshot, Citation, Publisher types with Get/Store DB methods, tag/category management, metadata ops, YAML import - blob: content-addressable store (SHA256, hierarchical dir layout) - proto: protobuf definitions (common.proto, artifacts.proto) with buf linting and code generation - server: gRPC ArtifactService implementation (create/get artifacts, store/retrieve blobs, manage tags/categories, search by tag) All FK insertion ordering is correct (parent rows before children). Full test coverage across artifacts, blob, and server packages. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
