Add issue triage agentic workflow

[Copilot]

Adds a GitHub Agentic Workflow (gh-aw) that automatically triages newly opened issues: classifying type, detecting duplicates, and requesting missing info when the description is unclear.

Workflow: issue-triage

Trigger: issues: opened

Steps (in order):

• Fetch full issue details via GitHub API
• Search open/closed issues for duplicates → label duplicate + comment + stop
• Classify type → bug / enhancement / feature-request / question / documentation
• Evaluate clarity → label needs-more-info + targeted clarifying comment if description is insufficient

Safe outputs used: add-labels, add-comment, update-issue — main job runs with issues: read only; write operations delegated to separate safe-output jobs.

Network: restricted to api.github.com.

Files

• .github/workflows/issue-triage.md — workflow definition (editable at runtime without recompilation)
• .github/workflows/issue-triage.lock.yml — compiled GitHub Actions YAML (generated, do not edit)
• .gitattributes — marks lock files as linguist-generated

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/actions/github-script/git/ref/tags/v8
  • Triggering command: /usr/bin/gh gh api /repos/actions/github-script/git/ref/tags/v8 --jq .object.sha (http block)
• https://api.github.com/repos/github/gh-aw/git/ref/tags/v0.53.2
  • Triggering command: /usr/bin/gh gh api /repos/github/gh-aw/git/ref/tags/v0.53.2 --jq .object.sha (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
