feat(artifacts): add S3-based artifact management system
Implement artifact storage and distribution for θ-cycle outputs: - src/artifacts/types.ts: Artifact, ArtifactMetadata interfaces * ArtifactType enum (file, code, report, image, log, json) * SaveArtifactOptions, DownloadUrlOptions, ArtifactFilter - src/artifacts/manager.ts: S3 + DynamoDB client * save() / saveFile() - Upload to S3, store metadata in DynamoDB * getDownloadUrl() - Generate presigned URL (default: 1 hour) * get() - Retrieve artifact metadata * listBySession() / listByUser() - Query artifacts * deleteArtifact() / deleteBySession() - Cleanup * initializeTable() - DynamoDB table setup - src/artifacts/manager.test.ts: Unit tests (skeleton) - src/artifacts/index.ts: Module exports Features: - S3 storage with automatic expiration - Presigned URLs for secure downloads - DynamoDB metadata with TTL (default: 24 hours) - GSI for sessionId/userId/type queries - Session-based cleanup Co-Authored-By: Claude <noreply@anthropic.com>
