Kyle Isom 94963bb8d6 Step 15: CLI wiring, prune, and sgardd daemon.
Local prune: garden.Prune() removes orphaned blobs. 2 tests.

CLI commands: sgard push, sgard pull (with SSH auth via --ssh-key
or ssh-agent), sgard prune (local by default, remote with --remote).

Server daemon: cmd/sgardd with --listen, --repo, --authorized-keys
flags. Runs gRPC server with optional SSH key auth interceptor.

Root command gains --remote and --ssh-key persistent flags with
resolveRemote() (flag > env > repo/remote file).
