test: tests para deteccion de pasos del pipeline en ProgressReporter

Tests unitarios para formatToolEvent con todos los pipeline hints:
create-full.sh, health-check.sh, notify-developer.sh, restart.sh,
start.sh, go build, go test, Edit, Read, Glob, Grep, y fallback
generico. Incluye tests para el contador de pasos y truncateInput.

Actualiza test de integracion existente para el nuevo formato de
mensajes (step counter + nombres legibles vs raw tool names).
