assignee-management.yaml

# This workflow manages issue assignments and related label changes:
# 1. When someone is assigned to an issue:
#    - Removes "stat:awaiting-triage" label
#    - Adds "stat:Investigating" label
# 2. When all assignees are removed from an issue:
#    - Adds "stat:awaiting-triage" label
#    - Removes "stat:Investigating" label
# 3. When "stat:Investigating" label is added:
#    - Automatically assigns the issue to the person who added the label
