set_trim_fades
Use for every cut, trim, fade-in, or fade-out instruction, including when it appears inside a mastering request. Update the non-destructive keep region and fade lengths while preserving the selected master. Values are validated against the loaded track duration; after a prior action, use that action’s returned stateVersion. Operates on the audio already loaded in the current Champagne browser page, so no chat attachment is required.
