Summary

• Adds GetHrInsightQuery MediatR handler that fetches live dashboard metrics and injects them into the LLM system prompt
• Adds HrInsightDto response DTO with Question, Answer, and ExecutionTimeMs
• Adds POST /api/v1/ai/hr-insight endpoint to AiController (guarded by [FeatureGate("AiEnabled")])
• Updates XML docs for the new endpoint

What this enables

HR managers can ask plain-English questions ("Which department has the most employees?") and get answers grounded in live workforce data — no hallucination, no manual data export.

How to test

1. Start Ollama: ollama serve
2. Set "AiEnabled": true in appsettings.json
3. Run API: dotnet run
4. Open Swagger at https://localhost:44378/swagger
5. POST to /api/v1/ai/hr-insight with { "question": "Which department has the most employees?" }
6. Verify response includes question, answer, and executionTimeMs
7. Set "AiEnabled": false — endpoint returns 503, all other endpoints unaffected
