Upload hooks: - StorageHooks class with fire-and-forget event emitter pattern - Events: upload, upload:error, delete, delete:error, download - All StorageClient operations now emit appropriate events - Unsubscribe functions for cleanup Metrics: - StorageMetricsCollector interface (decoupled from prom-client) - InMemoryMetrics for testing and local dev - attachMetrics() wires hooks to any collector automatically - Backends can create a Prometheus collector via MetricsService Presigned multipart upload (browser direct-upload): - createMultipartUpload() initiates and returns uploadId - getMultipartUploadUrls() generates presigned PUT URLs per part - completeMultipartUpload() finalizes with part ETags - abortMultipartUpload() for cleanup on abandoned uploads 90 tests passing across 5 test files.
