DemonGatanjieuandClaude Opus 5.5 72d3ca12ea Fix saves: run each save, not the canvas; keep Ctrl+Z after going back
ComfyUI-Manager wraps app.graphToPrompt and drops the graph, so every run and
the check before it compiled the canvas: same seeds, nothing of the later marks.
A result that is not the copy's is now made by ComfyUI's own method.

Going back is one of ComfyUI's undo steps, so Ctrl+Z returns to the state left
behind. A save can also open on a new tab, the empty canvas's menu and a + on
the bar keep one, and marks show as saves, runs counted as runs.

/**

* graph's id, node and name, and a workflow saved from the open canvas carries the canvas's
* id: configured under that id, the detached graph would share the canvas's widget values and
* write its own onto them. So the copy gets an id of its own. Its nodes' widgets still make
* DOM elements on ComfyUI's page (prompt boxes that showed at its top left), which only the
* nodes' removal takes away: read it through readDetached, which clears it afterwards.
