Automated issue triage workflow (#5419)

* Automated issue triage workflow

* Bump dependencies

* Fix issue-triage workflow: security, reliability, and testability

Address six review comments on the issue-triage workflow:

1. Change trigger from issues:opened to issues:labeled so the
   secret-backed triage flow is only triggered by a maintainer-
   controlled signal.

2. Include inputs.issue_number in the concurrency group so
   workflow_dispatch runs for the same issue are properly
   de-duplicated.

3. Improve team membership error handling to fail closed: verify
   the team exists before checking membership, and only treat a
   404 as 'not a member' (all other errors fail the job).

4. Use optional chaining (issue.user?.login) for the API-fetched
   issue to handle deleted GitHub accounts without crashing.

5. Extract the inline github-script into a testable module at
   .github/scripts/check_team_membership.js with 10 tests in
   .github/tests/test_check_team_membership.js covering all
   code paths (payload/API author resolution, deleted accounts,
   team lookup failure, 404 vs non-404 membership errors).

6. Make the spam gate actually stop the job by exiting non-zero
   instead of just logging, so future steps cannot accidentally
   run for spam issues.

* Make issue-triage workflow manually triggered only for initial testing

Remove the 'issues' event trigger, keeping only 'workflow_dispatch' so the
workflow can be tested manually before enabling automatic triggers.
