README: Model Check finds renamed models by the fingerprints in the workflow

Without them it can only offer a file of the same name; the setting that
records them is named.

+**2. Someone else's workflow opens with red nodes.** Model Check says which models are missing. When the workflow carries model fingerprints (the plugin writes them into the workflows and images of everyone who has it, unless they turn it off), the ones you already have under another name or in another folder go back in with one press, and the rest can be downloaded from Civitai or Hugging Face, each download checked against its fingerprint. A workflow without fingerprints can only be matched by file name: a file of the same name elsewhere on your computer is offered for you to confirm.

 * **Current node** (formerly Node Assistant) shows the model of the node you select, lets you swap it from the covers or insert a LoRA, and lists every set of values saved for that kind of node with exactly what applying it would change; saved values can be deleted there.
 * **Each tool on its page**: share and import on Workflows (⇅: a short share code of the canvas workflow, in Chinese characters or letters; paste a code, or drop a workflow file, an image or a backup .zip), Model Sources (where each model can be downloaded) on Models and in Model Check, translation on the prompt boxes in Current node.
 * **Settings** (at the bottom): language, font size, thumbnails, video covers, which model folders to show, and feedback. Home and Settings have **Report a problem**, which opens a GitHub issue with your versions and GPU already filled in.
