Send a weekly Keephub task progress report to Slack

This workflow fetches all Keephub task templates active in the
previous week for a given org unit, retrieves detailed progress
for each one, and posts a formatted summary to Slack every Monday
at 9:00am.

Each task is shown with its completion percentage and counts,
grouped by status:
🔴 Overdue — tasks past their due date with no completions
🟡 Open — tasks in progress
✅ Done — fully completed tasks

A totals summary line is included at the top of every report.

Prerequisites

• Keephub account with Login API credentials
  OR Keephub Bearer API token
• Slack workspace with a channel for reports

Setup

1. Connect your Keephub Login or Keephub Bearer credential to the "Get Tasks by
   Orgunit" node
