fix: pin deployment-operator grpc dependency

[plural-copilot]

Summary

• pin google.golang.org/grpc explicitly in go/deployment-operator/go.mod
• keep deployment-operator on grpc v1.80.0, which is above the scanner-recommended fixed version 1.79.3
• verify the Docker build path resolves the fixed grpc version for the deployment-operator image

Rationale

The vulnerable image reported grpc v1.72.2, but the current repository lock data for deployment-operator already resolves grpc v1.80.0. Making grpc a direct requirement in the deployment-operator module prevents the image build from drifting to an older vulnerable transitive selection and documents the intended fixed version clearly in the module manifest.

Verification

• inspected go/deployment-operator/go.mod and go.sum for resolved grpc version
• confirmed go/deployment-operator/go.sum contains google.golang.org/grpc v1.80.0
• started deployment-operator Docker build and confirmed it consumes the updated module manifest
• started an in-container go build ./cmd/agent/... using golang:1.26.3-alpine3.22; first-time dependency population was very large, but the module resolution showed grpc v1.80.0

Greptile Summary

This PR pins google.golang.org/grpc as a direct dependency in go/deployment-operator/go.mod to prevent future go mod tidy runs from drifting to an older transitive version. The resolved version stays at v1.80.0 (already present in go.sum); only the // indirect annotation is removed.

• The annotation removal is semantically correct — google.golang.org/grpc is directly imported in pkg/scm/grpc_client.go, pkg/scm/grpc_server.go, and related files.
• The entry was not moved into the top-level direct-dependencies require block; it remains in the indirect block without its annotation, leaving the manifest in a slightly inconsistent state until go mod tidy is run.

Confidence Score: 4/5

Safe to merge; the resolved grpc version is unchanged and the module already had grpc v1.80.0 locked in go.sum.

The only change is removing // indirect from a single line. The grpc version was already v1.80.0 before this PR and grpc is genuinely directly imported, so the annotation removal is correct. The minor inconsistency of the entry remaining in the indirect require block instead of being moved to the direct-dependency section is cosmetic and would be cleaned up by a routine go mod tidy.

No files require special attention beyond the cosmetic placement note on go/deployment-operator/go.mod.

Important Files Changed

Filename	Overview
go/deployment-operator/go.mod	Promotes google.golang.org/grpc v1.80.0 from indirect to direct dependency by removing the // indirect annotation; version is unchanged and grpc is genuinely imported directly in the module, so the annotation removal is correct, but the entry was not moved to the direct-dependencies block.

Entry lives in the indirect require block

The // indirect annotation was removed, but the entry was not moved into the direct-dependencies require block at the top of the file. Running go mod tidy will notice that google.golang.org/grpc is directly imported (e.g. in pkg/scm/grpc_client.go) and relocate it to the first require block — but until then the file is inconsistent. While this does not affect the resolved version, it could confuse developers scanning the module manifest and is not the idiomatic Go Modules format. Consider running go mod tidy and committing the reorganized output alongside this change.
