SxCP is the Prompt-Builder pack's brand; these are Calibrator nodes. Renamed the display names (cosmetic only — class_types unchanged, so no workflows/bridge break): 'External Prompt (Receptor)', 'Audio Prompt Guide', 'Audio Wave + Segments'; renamed the JS extension id too. Kept the genuine Prompt-Builder (SxCP) references in the docs. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
