Add automated GitHub Action for issue and comment moderation based on team membership

[Copilot]

This PR implements an automated moderation system that restricts issue creation and commenting to authorized team members only.

Problem

The repository needed a way to automatically control who can create issues and add comments, ensuring only members of designated teams have access to these features.

Solution

Added a GitHub Action workflow that:

• Monitors issue creation: When someone opens a new issue, checks if they're a member of authorized teams
• Monitors comment creation: When someone adds a comment, verifies their team membership
• Takes automatic action: For non-team members:
  • Issues: Closes the issue and adds an explanatory comment
  • Comments: Immediately deletes the comment

Implementation Details

Files Added

• .github/workflows/issue-moderation.yml - Main workflow that handles the moderation logic
• .github/ISSUE_MODERATION.md - Documentation explaining configuration and usage

Key Features

• Team-based access control: Uses GitHub organization teams for membership verification
• Configurable teams: Easy to modify which teams are authorized via the allowedTeams array
• User-friendly feedback: Provides clear explanations when issues are closed
• Comprehensive logging: Detailed logs for all moderation activities
• Proper permissions: Minimal required permissions (issues: write, contents: read, metadata: read)

Configuration

The workflow comes pre-configured with example teams (core-team, maintainers, admins). To customize for your organization:

const allowedTeams = [
  'your-actual-team-1',
  'your-actual-team-2',
  'your-actual-team-3'
];

Workflow Triggers

• issues: [opened] - Activates when new issues are created
• issue_comment: [created] - Activates when new comments are added

The action will begin automatically moderating issues and comments as soon as this PR is merged to the main branch.
