# SpecWeave Azure DevOps Sync Hook
# Runs after task completion to sync progress to Azure DevOps Work Items
#
# This hook is part of the specweave-ado plugin and handles:
# - Syncing task completion state to Azure DevOps work items
# - Updating ADO work item status based on increment progress
#
# Dependencies:
# - Node.js for running sync scripts
# - jq for JSON parsing
# - metadata.json must have .ado.item field
# - Azure DevOps PAT in .env
