Build the knowledge graph pillar with the kg package: - Node: hierarchical notes with parent/children, C2 wiki-style naming, shared tag/category pool with artifacts - Cell: content units (markdown, code, plain) with ordinal ordering - Fact: EAV tuples with transaction timestamps and retraction support - Edge: directed graph links (child, parent, related, artifact_link) Includes schema migration (002_knowledge_graph.sql), protobuf definitions (kg.proto), full gRPC KnowledgeGraphService implementation, CLI commands (node create/get), and comprehensive test coverage.

**Deliverables:**
|
|
- [x] `artifacts` package: `Artifact`, `Snapshot`, `BlobRef`, `Citation`, `Publisher` types with `Get`/`Store` methods

|
|
- [x] Metadata store/retrieve operations (`StoreMetadata`/`GetMetadata`)
|
|
- [x] `blob` package: Content-addressable blob store (SHA256 hashing, hierarchical directory layout, read/write/exists)
|
|
- [x] YAML import: `ArtifactYAML`, `SnapshotYAML`, `CitationYAML` with `ToStd()` conversions and `LoadArtifactFromYAML`
|
|
- [x] Protobuf message definitions for all artifact types (`proto/exo/v1/common.proto`, `proto/exo/v1/artifacts.proto`)
|
|
- [x] gRPC service: `ArtifactService` with create/get artifacts, store/retrieve blobs, manage tags/categories, search by tag
|
|
- [x] `server` package: Full gRPC service implementation with proto-domain conversion helpers
|
|
- [x] buf.yaml for proto linting, buf.gen.yaml for code generation
|
|
- [x] Full test coverage for all packages (artifacts, blob, server)
