Establish the project foundation with three packages: - core: shared types (Header, Metadata, Value, ObjectType, UUID generation) - db: SQLite migration framework, connection management (WAL, FK, busy timeout), transaction helpers (StartTX/EndTX), time conversion - config: runtime configuration (DB path, blob store, Minio, gRPC addr) Includes initial schema migration (001_initial.sql) with 13 tables covering shared infrastructure, bibliographic data, and artifact repository. Full test coverage for all packages, strict linting (.golangci.yaml), and Makefile. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
