feature: Return the image hash with final gRPC message

[fintelia]

This adds an additional field to the Completed message returned by the gRPC server when streaming an image finishes that indicates the sha384 of the image that was streamed.

[Copilot]

Pull request overview

This PR extends Trident’s gRPC servicing completion response to optionally include the SHA-384 (formatted as sha384:<hex>) for the image involved in the operation, and threads that value through the server task execution pipeline.

Changes:

• Adds optional string image_hash to trident.v1.Completed protobuf message.
• Updates servicing task plumbing to propagate an optional Sha384Hash from operations into the final Completed response.
• Updates Trident install/update/stream_image to return (ExitKind, Option<Sha384Hash>) and adapts gRPC handlers / CLI call sites accordingly.

nit: bump harpoon-proto to 1.1?

Pull request overview

This PR extends the gRPC Completed message to optionally include the SHA-384 (metadata) hash of the OS image associated with a streamed servicing operation, and plumbs that value through the server/task execution path.

Changes:

• Add optional string image_hash = 4 to Completed in the servicing proto.
• Thread an Option<Sha384Hash> through servicing task execution and set Completed.image_hash (formatted as sha384:<hash>).
• Bump trident-proto crate version to reflect the wire/API change.
