Add issue triage agentic workflow

[Copilot]

Adds a GitHub Agentic Workflow (gh-aw) that automatically triages newly opened issues.

Workflow behavior (issue-triage.md)

• Triggers on issues: opened for all GitHub users (roles: all)
• Labels by type: bug, enhancement, documentation, question, performance
• Labels by priority: priority:high, priority:medium, priority:low
• Duplicate detection: searches open + closed issues (last 6 months); comments with a link and adds duplicate label if found
• Clarification requests: adds needs-info and posts a targeted comment when a bug is missing repro steps/version info or a feature request lacks motivation
• Assignment: assigns clearly-scoped issues to @eiriktsarpalis; skips duplicates and needs-info issues
• Uses noop safe output to signal triage complete when no action is required

Security notes

• Issue body is read via GitHub API tools — not injected as a template expression — to prevent script injection
• Minimal permissions (issues: read, contents: read); all write operations go through safe-outputs (add-comment, update-issue)
• lockdown: false intentionally set to allow processing issues from non-team members (standard for triage workflows)

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/graphql
  • Triggering command: /usr/bin/gh gh label list (http block)
• https://api.github.com/repos/eiriktsarpalis/PolyType/collaborators
  • Triggering command: /usr/bin/gh gh api repos/eiriktsarpalis/PolyType/collaborators (http block)
• https://api.github.com/repos/github/gh-aw/git/ref/tags/v0.50.4
  • Triggering command: /usr/bin/gh gh api /repos/github/gh-aw/git/ref/tags/v0.50.4 --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)
