Fase 2: Query Store analysis (plan regressions, failed forced plans, parameter sensitivity)
Collector reads the 100 heaviest queries per Query Store database, split
into the last 24 hours and the week before. Rules:
- SQLI-QS-001 plan regression: new plan >= 2x slower than the best plan
  from the week before and >= 60 s extra per day; scripts the force
- SQLI-QS-002 forced plan that fails (e.g. NO_INDEX); scripts the unforce
- SQLI-QS-003 parameter sensitivity: very different plans or volatile
  durations; suggests PSP optimization / Query Store hints on 2022+
Also: backups taken in the same second a database was created count.
