mt-release.yml: trigger record-screenshot workflow when screenshots are stale (>3 months)

[Copilot]

After a release completes, mt-record-screenshots.yml should auto-trigger when the phone screenshots haven't been updated in over 3 months.

Changes

• mt-release.yml — two new steps appended after MT Publish release:
  • MT check screenshot age: inspects git log timestamp on app-android/src/main/play/listings/en-US/graphics/phone-screenshots; sets TRIGGER_SCREENSHOTS=true if the directory is missing, has no commits, or the latest commit is >90 days old
  • MT trigger record screenshots workflow: conditionally dispatches mt-record-screenshots.yml on the current branch via gh workflow run

- name: MT check screenshot age
  id: mt-check-screenshot-age
  run: |
    SCREENSHOT_DIR="app-android/src/main/play/listings/en-US/graphics/phone-screenshots"
    THREE_MONTHS_DAYS=90
    THREE_MONTHS_SECONDS=$(( THREE_MONTHS_DAYS * 24 * 60 * 60 ))
    if [[ ! -d "$SCREENSHOT_DIR" ]]; then
      echo "TRIGGER_SCREENSHOTS=true" >> $GITHUB_OUTPUT
    else
      LAST_COMMIT_TIMESTAMP=$(git log -1 --format="%ct" -- "$SCREENSHOT_DIR" 2>/dev/null)
      # ... age comparison, sets TRIGGER_SCREENSHOTS accordingly
    fi

- name: MT trigger record screenshots workflow
  if: ${{ steps.mt-check-screenshot-age.outputs.TRIGGER_SCREENSHOTS == 'true' }}
  run: gh workflow run mt-record-screenshots.yml --ref "${{ env.MT_BRANCH_NAME }}"
  env:
    GH_TOKEN: ${{ secrets.MT_PAT }}

The existing fetch-depth: 0 checkout ensures full git history is available for the age check.
