fix(voz): frases desativadas em sequência deixavam fatias sobrando no corte

phrase_review_to_actions() cortava cada frase desativada isoladamente
(start..end da própria frase) — quando várias seguidas estavam desativadas,
a pausa ENTRE elas não pertencia a nenhuma frase e sobrevivia como um
clipe minúsculo (0,1-0,5s) na timeline final. Confirmado no projeto
Mastopexia real: 29 cuts individuais geravam mais de uma dezena de fatias
sub-segundo; agrupar frases desativadas consecutivas num único cut (do
início da primeira ao fim da última) reduziu para 3 cuts e 4 fatias
residuais (menores, provavelmente do padding do remove_media_silence —
registrado como dívida separada em 09_MANUTENCAO.md §2.5).
