Adds a streaming read method to the Storage abstraction so callers can pull object bytes without forcing a full in-memory load. S3Storage wraps GetObject; LocalStorage opens the file with path-traversal and sidecar guards. Tests cover happy path, traversal rejection, sidecar rejection, and missing key. Used in the next commit by the attachment-preview proxy endpoint. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
