[dependabot:release-train-updater] Go module patch update ready for review: pflag v1.0.10, grpc v1.83.2

Review-mode dependency maintenance bundle for target repository `github/gh-aw-mcpg` (main branch). This run operates in `review` mode, so no PR was opened directly against the target; a review bundle artifact was published instead.

### Summary
- Ecosystem: Go modules
- Manifests: `go.mod`, `go.sum`
- Updates (indirect, patch-level):
- `github.com/spf13/pflag` v1.0.9 → v1.0.10
- `google.golang.org/grpc` v1.83.1 → v1.83.2
- Validation: `go build ./...` succeeded; `go test` on all non-integration packages passed (28 packages ok). Integration tests under `test/integration` require a prebuilt `awmg` binary via `make build` (pre-existing local requirement) and were not exercised.
- Risk: low — both are transitive/indirect deps, patch-level bumps, no source changes needed.
- Merge candidate: yes (non-major, clean resolution, tests passing, no suspicious scripts)

### Artifacts
A review bundle (patch file, summary, changed-files list, validation log) was published via `publish_review_bundle` for `github/gh-aw-mcpg`, intended safe-output primitive `create-pull-request`.

### Control Plane

Start with the published review bundle and inspect go.mod and go.sum for the pflag and grpc version changes. Run go build ./... and go test for the non-integration packages; done means both indirect dependencies resolve cleanly and the reported validation remains passing, while integration tests require make build and the prebuilt awmg binary.
