All configuration is now auto-computed at sampling time - no user-facing
settings except the optional total_frames INT. Window count is derived
from the number of conditioning entries Refiner/Studio outputs. Window
size is total_frames (or actual latent size) / num_windows. Boundaries
are placed at equal intervals. split_conds_to_windows always on.
Studio: move split_by_transitions from direct node input to the Refiner
tab in the popup editor. Removed direct input, added toggle + hint text.
