The curl command lacks error handling and will silently fail if the Slack webhook call fails. Add the --fail flag to make curl return a non-zero exit code on HTTP errors:

curl -X POST -H 'Content-type: application/json' \
  --fail \
  --data '{
    ...
  }' \
  ${{ secrets.SLACK_WEBHOOK_URL }}

This ensures the workflow step fails if the Slack notification cannot be sent.

Added the --fail flag to the curl command in e820b44. Also added the workflow_dispatch trigger with force_run input and updated the week check logic to bypass the schedule check when manually triggered.
