fix(tts): prevent double [pause] in xAI auto speech tags for multi-paragraph text

Browse source 
_apply_xai_auto_speech_tags runs two independent transformations:
  1. paragraph breaks (\n\n) → " [pause] "
  2. first-sentence boundary → " [pause] "

Both fired unconditionally, so multi-paragraph input produced
"Hello world. [pause] [pause] Second paragraph." — an unnatural
double pause in the TTS audio.

Guard the first-sentence substitution with _XAI_SPEECH_TAG_RE.search(clean):
if the paragraph pass already inserted a [pause] tag, skip the
first-sentence pass. Single-paragraph behavior is unchanged.
