1. create an AI triage workflow for issues and PRs.

[Gujiawei-Edinburgh]

Summary

This PR adds an AI-assisted triage workflow for GitHub Issues and PRs to help identify low-signal / low-quality submissions early and apply consistent triage labels.

How it works

• Triggered on issues and pull_request_target (opened, edited, reopened)

• Reads the issue / PR title and body from the GitHub event payload

• Calls an LLM service to classify:

  • how actionable the content is
  • whether it looks low-signal or AI-generated

• If the AI call fails, falls back to simple heuristics (missing repro, version, logs, etc.)

Labeling policy

Based on model scores and thresholds:

• Low-signal → triage:needs-info, triage:low-signal
• Likely AI-generated → triage:suspected-ai (+ triage:needs-info)
• Only missing labels are added (no relabel churn)

Commenting policy

• Issues: may add a short, friendly checklist comment asking for missing info
• Pull Requests: labels only, no automated comments (reviewers handle discussion)

Safety

• Limits input size sent to the model
• Limit concurrency for actions
