chore: Add workflow to auto-label community PRs from forks

[Aaron ("AJ") Steers (aaronsteers)]

Summary

Adds a GitHub Actions workflow that automatically applies the community label to PRs opened from forks. This enables automatic tracking on the Community PRs project board.

The workflow:

• Triggers on pull_request_target events (opened and reopened)
• Only runs for PRs from forks (via if: github.event.pull_request.head.repo.fork == true)
• Uses the actions-ecosystem/action-add-labels marketplace action (v1.1.3, pinned by SHA)
• The action's addLabels API is idempotent—if the label already exists, it succeeds without error

Review & Testing Checklist for Human

• Verify the workflow does NOT checkout or execute any code from the fork (security requirement for pull_request_target)
• Confirm the community label exists in this repository
• Verify the pinned action SHA (bd52874380e3909a1ac983768df6976535ece7f8) matches v1.1.3

Test plan: After merging, open a PR from a fork (or close/reopen an existing fork PR) to verify the label is applied automatically.

Notes

This workflow cannot be tested via CI since it only triggers on actual fork PRs.

Received message in Slack channel #community-open-source:

@Devin - Please update our workflows so that new PRs from forks automatically are labeled (in not already) and we'll auto-add by label to a specific project board (projects v2).

📝 Walkthrough

Walkthrough

A new GitHub Actions workflow was added to label pull requests from forked repositories with the "community" label on opened and reopened events; it checks that the PR head repo is a fork and applies the label idempotently via an action.

Changes

Cohort / File(s)	Summary
GitHub Actions Workflow .github/workflows/label-community-prs.yml	Added workflow triggered on pull_request_target (opened, reopened). Runs on ubuntu-24.04, gated to run only when the PR head repository is a fork, and applies the community label using actions-ecosystem/action-add-labels with write permissions for issues and pull-requests.

Estimated code review effort

🎯 1 (Trivial) | ⏱️ ~3 minutes
