Subject: [PATCH] =?UTF-8?q?feat:=20mid-flow=20audio=20=E2=80=94=20transcri?=

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a user sends audio while in an active flow (__cap, __foreach,
collecting, __api_vars), the Whisper transcription is passed directly
to NormalBot as the step answer instead of going through NLU routing.

Bot still shows '🎤 Escuché: _texto_' confirmation before processing.
