Sessões com outcome=interrupted e ≥10 eventos são redirects naturais
do utilizador, não falhas da skill. O detector contava todas as
interrupções como falhas, gerando falsos positivos para skills
conversacionais como superpowers:brainstorming.

Fix: só contar como falha erros reais (outcome=error) ou interrupções
precoces (<10 eventos).

Resolve ticket #10407.
