New 'seed' input seeds sampling (torch.manual_seed before generation) so a fixed seed
reproduces the same output — no reroll when re-queueing while tweaking downstream nodes;
bump it to reroll (named 'seed' so the frontend adds control_after_generate). Generation
now honors ComfyUI cancel: a StoppingCriteria halts model.generate() promptly and
_check_interrupt() raises between passes. Workflows updated with the seed widget.

Rebuilt around the real model: group_frames (721) are HARD splits; segments = user
splits UNION the group lines, so a segment never crosses a group boundary (last segment
in a group ends exactly on frame 721). segment_select is now a RANGE string ('A-B' /
'N' / '' = all) that crops waveform_image + audio + summary to segments A..B. Render
rewritten: mirrored waveform (uses top+bottom), bold group grid, thin segment lines,
labels along the top and notes along the bottom, selected range shaded. JS: guards
frame values (0 -> default, fixing the 400+-segments-on-reload explosion), writes only
USER splits to segments_json, dblclick=add split / shift-click=remove / click=seek.
group number fixed (boundary rounding). Workflows + README updated.

Pivot to the user's model: segments are a fixed grid of subsegment_frames frames
(default 721 @ 24fps = one LTX clip), not arbitrary clicks. New inputs:
subsegment_frames (grid size) and segment_select (0=all, N=output ONLY chunk N —
crops waveform_image, AUDIO, and summary so you can generate/skip one beat at a time).
_render gains window-crop + frame markers + per-segment time/frame labels. JS rewritten:
draws the fixed grid, auto-fills the notes box with one segN: line per chunk (type or
dblclick to note), click-to-seek, playhead + time readout. Workflows updated for the
new widgets.

The canvas Load expects the UI graph format (nodes[]+links[]+positions), not the
API format — so the _api.json came up empty. Added workflow_ltx_audio.json in UI
format (matched the schema from a real workflow: node dicts with pos/size/inputs/
outputs/widgets_values, link tuples, version 0.4), validated slots/links. Dropped
audio_upload from AudioWaveSegments so the widget layout is predictable (the JS
upload button stays). README points to the loadable file; _api.json kept for the bridge.
