[dependabot:release-train-updater] Dependency update ready for review: spf13/pflag v1.0.9 → v1.0.10 (target: github/gh-aw-mcpg)

**Review mode — artifact-backed bundle, no live PR created.**

**Action:** A maintainer with write access to `github/gh-aw-mcpg` should review the attached patch and, if satisfied, apply it via a normal PR (e.g. cherry-pick `go.mod`/`go.sum` changes and run `go mod tidy`). Acceptance check: `go build ./...`, `go vet ./...`, `make build`, and `go test ./...` all pass, matching validation already performed here.

## Summary
Target repository `github/gh-aw-mcpg` has one low-risk, high-confidence dependency update available: the indirect Go module `github.com/spf13/pflag` (pulled in transitively via `github.com/spf13/cobra`) can be bumped from v1.0.9 to v1.0.10, a patch release. No source code in the repository imports `pflag` directly — it is consumed entirely through `cobra`. This is a routine-freshness lane pick, chosen as the smallest, most isolated, lowest-risk candidate among the outdated modules reported by `go list -m -u all` (other outdated modules are transitive pins from `modelcontextprotocol/go-sdk` and would require broader, riskier changes).

## Validation performed
- `go get github.com/spf13/pflag@v1.0.10` + `go mod tidy`
- `go build ./...` — success
- `go vet ./...` — success
- `make build` — built `awmg` binary successfully
- `go test ./...` — **all packages passed**, including the full `test/integration` suite

## Review bundle
The full diff (`go.mod`/`go.sum`), a detailed summary with risk assessment, and validation logs have been published as a workflow artifact (`publish_review_bundle`, bundle name `pflag-1.0.10`) for `github/gh-aw-mcpg`. Retrieve it from this workflow run's artifacts.

Agent prompt (for a coding agent working directly in github/gh-aw-mcpg)

```
Bump the indirect Go dependency github.com/spf13/pflag from v1.0.9 to v1.0.10 in this repository.

1. Run: go get github.com/spf13/pflag@v1.0.10
2. Run: go mod tidy
3. Validate: go build ./..., go vet ./..., make build, go test ./...
4. Open a PR with only go.mod and go.sum changed, and a summary noting this is a patch-level, indirect (transitive via cobra) update with no direct source usage and no test failures.
```

Risk: low. Confidence: high. `Smart-Dependabot-Merge-Candidate: yes` (per bundle metadata) — still requires human review and merge; not auto-merged.

Review the go.mod and go.sum diff in the pflag-1.0.10 workflow artifact, then run go mod tidy if needed. Validate with go build ./..., go vet ./..., make build, and go test ./...; done means only the dependency metadata changes are required and all checks pass.
