The workflow’s activation/permission model appears misaligned with “run on new issues” expectations for public issue reporters, and the generated workflow grants broader write permissions than necessary (PR write) for an issues-only workflow.

Pull request overview
This PR adds the Duplicate Surfacing GitHub Agentic Workflow to winget-create, mirroring the pilot already used in winget-cli, so new issues can be scanned for likely duplicates and (optionally) labeled/commented for maintainer review.
Changes:
- Adds the Duplicate Surfacing agentic workflow source (
duplicate-surfacing.md) and its compiled lock workflow (duplicate-surfacing.lock.yml). - Adds the agentic workflow actions lockfile (
.github/aw/actions-lock.json) and marks lock workflows as generated in.gitattributes. - Updates the spelling action configuration (exclude compiled artifacts; allow a few workflow-specific terms).
File summaries

| .github/workflows/duplicate-surfacing.lock.yml | Generated compiled workflow implementing the agentic workflow runtime and safe-outputs handling. |
| .github/aw/actions-lock.json | Pins the gh-aw setup action SHA used during compilation. |
| .github/actions/spelling/excludes.txt | Excludes gh-aw compiled artifacts and lock workflows from spellchecking noise. |
| .github/actions/spelling/allow.txt | Adds allowed workflow-specific tokens that appear in the workflow text. |
| .gitattributes | Marks lock workflows as generated and configures merge behavior for them. |

Ports the gh-aw Duplicate Surfacing workflow from microsoft/winget-cli (PRs #6400, #6408, #6410) to winget-create. On newly opened issues, an agent searches existing issues and, when it finds a likely duplicate, applies the Possible-Duplicate label and posts an advisory comment for maintainer review. It never closes issues or applies duplicate-close triggers (detect-only). Includes the two winget-cli refinements: no-op runs are not reported as tracking issues (noop.report-as-issue: false), and search guidance mandates high-recall in:title queries to surface old, sparse-body duplicates. Adds autodetect, noop, PreIndexedPackage, and toolsets to the spelling allow list for the workflow prompt text.

The compiled duplicate-surfacing.lock.yml and .github/aw/ artifacts are machine-generated (marked linguist-generated) and embed tool names, CA bundle identifiers, and other tokens that are not real English words. Exclude them from Check Spelling rather than polluting the dictionary. Also allow the #NNN placeholder used in the workflow prompt text.

📖 Description
Ports the Duplicate Surfacing agentic workflow (
gh aw) from microsoft/winget-cli (PRs #6400, #6408, #6410) towinget-create.When a new issue is opened, an agent searches existing issues and, if it finds a likely duplicate, applies a
Possible-Duplicatelabel and posts an advisory comment linking the candidate for maintainer review. It is detect-only — it never closes issues or applies duplicate-close triggers.This is the first Tier-1 pilot of rolling the workflow out across the winget repo family. Both winget-cli refinements are included:
noop.report-as-issue: false).in:titlequeries so old, sparse-body duplicates surface reliably.Changes:
.github/workflows/duplicate-surfacing.md— agentic workflow source (portable via${{ github.repository }})..github/workflows/duplicate-surfacing.lock.yml+.github/aw/actions-lock.json+.gitattributes— compiled artifacts (gh aw compile)..github/actions/spelling/allow.txt— addsautodetect,noop,PreIndexedPackage,toolsets.Possible-Duplicatelabel (amber#FBCA04) has been created on the repo.Created with GitHub Copilot assistance.
