dockerode/lib/docker.js required './session' at module scope, which pulls in
@grpc/grpc-js and @grpc/proto-loader - 112 files. Its single call site is inside
Docker.prototype.buildImage, the BuildKit path. Homarr lists, starts and stops
containers and never builds images, so every install with a Docker widget paid for
a gRPC stack it cannot reach.
Measured with a forced GC, in context rather than in a bare process: requiring
dockerode goes from +26.6 MiB RSS / 5.2 MiB heap to +20.6 MiB / 2.7 MiB, with grpc
and protobufjs files going 63 and 49 to zero.
The bare-process figure was +24.1 MiB, and quoting that would have overstated the
win by 4x - most of it overlaps with what dockerode loads anyway. The patch comment
records the in-context number.
