build: automatically triage issues

[kikoso]

Summary

This PR introduces an automated triage system powered by the Gemini 2.5 Flash model. It automatically assesses the priority of new Issues and applies appropriate GitHub labels to streamline the project management process.

Changes

• New Workflow: Added triage-issue.yml which triggers on Issue events (opened, edited) and workflow_dispatch.
• Restricted Scope: Unlike previous iterations, this is now restricted to Issues only to keep PR workflows clean.
• Triage Script: Added triage_issue.py to handle the interaction with the Gemini API using urllib.request (zero external dependencies).
• Automated Labeling: The system is specifically optimized to detect and apply Priority labels:
  • Priority: priority: p0 (Critical) through priority: p4 (Low).
• Security: Updated workflow permissions to minimal scope (issues: write, contents: read).

Setup Required

To enable this feature, a GEMINI_API_KEY must be added to the repository secrets.

Verification Results

• Issue Detection: Verified that the workflow correctly picks up title and body from issue events.
• Label Filtering: Confirmed that only priority:* labels suggested by the AI are applied, preventing unwanted label clutter.
• PR Exclusion: Verified that pull request events do not trigger this workflow.

This has been implemented in android-maps-compose.
