Replace the monolithic dependency-update.yml with three per-ecosystem agentic workflow source files compiled via gh aw compile: - dependency-update-dotnet.md (.NET / NuGet) - dependency-update-node.md (Node / npm / pnpm) - dependency-update-github-actions.md (GitHub Actions) Each workflow runs Copilot with: - Read-only agent token (no write permissions in agent job) - Network firewall scoped to the ecosystem's required domains - Safe outputs for create-pull-request (max 10, preserve-branch-name, recreate-ref), close-pull-request (max 10), and add-labels (max 30) - Existing skills and prompt files referenced as-is from the workspace The weekly Friday 09:00 UTC schedule and workflow_dispatch trigger are preserved on each individual workflow. COPILOT_TOKEN secret continues to be used via engine.env mapping. Closes #1064 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Pull request overview
This PR migrates the repository’s dependency-update automation from a single Copilot-CLI-driven workflow (with write tokens in the agent job) to three per-ecosystem GitHub Agentic Workflows (gh-aw) with compiled, pinned .lock.yml workflows, reducing prompt-injection and credential exposure risk.
Changes:
- Removed the monolithic
.github/workflows/dependency-update.ymlworkflow. - Added per-ecosystem agentic workflow sources (
.md) and their compiled.lock.ymlworkflows for .NET, Node, and GitHub Actions. - Added
.github/aw/actions-lock.jsonand marked.lock.ymlworkflows as generated in.gitattributes.

Summary
Closes #1064
Replaces the monolithic
dependency-update.yml(which ran Copilot CLI directly with write tokens, creating a structural prompt injection risk) with three per-ecosystem GitHub Agentic Workflow source files compiled to hardened.lock.ymlfiles.Changes

The compiled
.lock.ymlfiles reference one new restricted secret:COPILOT_GITHUB_TOKENenvironment variable expected by the gh-aw Copilot engine viaengine.env. No new credentials are introduced.No new actions or redirects beyond those pinned in
.github/aw/actions-lock.json(actions/github-script@v9.0.0andgithub/gh-aw-actions/setup@v0.74.8), both standard gh-aw runtime dependencies.Acceptance criteria
