Add "Tracking Template Evolution" section to repo-consistency agent

[Copilot]

Pull Request

Description

Applies the improvement from TemplateDotNetLibrary PR #10 to this template repository.

Adds a Tracking Template Evolution section to .github/agents/repo-consistency-agent.md — a systematic 4-step workflow instructing the agent to review recent merged PRs from demaconsulting/TemplateDotNetTool when assessing downstream projects, ensuring structural/configuration improvements aren't silently missed.

All other recent Library PRs (#3–#9) were already reflected in this repository.

3. Check whether each change is already present in the downstream project
4. Recommend missing updates with PR references and rationale
