refactor: comentarii strict functionale, fara referinte PRD/stories

Curatare globala a comentariilor si docstring-urilor (app, tools, teste,
scripturi): eliminate referintele la PRD-uri, US-xxx, task-uri istorice si
review-uri; pastrata doar informatia functionala, formulata scurt. Regula
adaugata in CLAUDE.md (sectiunea Stil). Fara modificari de cod sau comportament.
