Three agent files had a trailing comma after the last element in their
YAML flow-sequence tools arrays. When parsed, this produces an empty
string as an extra tool entry, which the Copilot API rejects with:
CAPIError: 400 Invalid 'tools[N].function.name': empty string
Affected files:
- agents/kusto-assistant.agent.md
- agents/mentoring-juniors.agent.md
- agents/address-comments.agent.md
