docs(interface): add an Autogrow Inputs page to the Interface Guide

[lin-bot23]

What

Adds a user-facing page for autogrow (dynamic) inputs to the Interface Guide:

• interface/features/autogrow-inputs.mdx (EN) plus zh / ja / ko
• docs.json: new entry in the Interface Guide, after interface/features/node-docs, for all four languages
• two new screenshots in images/interface/features/autogrow/

Until now the feature was only covered from the developer side (custom-nodes/v3_migration, custom-nodes/backend/node-replacement). Users who meet it in the graph (a node that grows another input when you connect the last one) had nothing to read.

Page contents

• what an autogrow input is and how the node grows when the last free input is connected
• that input order is the order the node receives values, and that the trailing free input is a placeholder
• a table of nodes that use autogrow inputs (Batch Images / Batch Masks / Batch Latents, And / Or, partner nodes with reference images such as Nano Banana 2)
• a tip linking to the V3 Autogrow template API for custom node authors
• a card linking to the Batch Images node reference

Screenshots

Both captured from a local ComfyUI 0.34.0 with frontend 1.51.9 (English UI), tight crop at 2x:

• autogrow-1.png: Batch Images with one connected input and one free input
• autogrow-2.png: after connecting the second input, the newly added free input is highlighted

Checks run locally

• check-anchors.py on all four files: OK
• check-structure-parity.ts (base origin/main): OK
• check-i18n-sync.mjs: all passed, no missing translations
• validate-links.py: OK
• sync-hash-i18n.ts: translationSourceHash synced on all three translations

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

📝 Walkthrough

The Interface Guide now includes Autogrow Inputs documentation in English, Chinese, Japanese, and Korean. The pages describe input expansion, ordering, placeholders, node-specific limits, and related documentation links.

Changes: Autogrow Inputs guides

Layer / File(s)	Summary
Localized guidance and navigation interface/features/autogrow-inputs.mdx, ja/interface/features/autogrow-inputs.mdx, ko/interface/features/autogrow-inputs.mdx, zh/interface/features/autogrow-inputs.mdx, docs.json	The four guides describe autogrow behavior, input ordering, placeholder slots, node-specific limits, and V3 Autogrow references. Navigation entries link to each guide.

Priority: ⬇️ Low

Merge Risk: 🔵 Low · up to 920b4

The new guides give input-limit guidance that conflicts with the existing node references. Align the localized tables so readers receive consistent information.

### Architecture Summary

@lin-bot23 , for screenshots, let's use Nodes2.0 by default. The mark you added isn't in the perfect position, and it's also too thin.

[lin-bot23]

Recaptured both screenshots with the modern Nodes 2.0 node design (Comfy.VueNodes.Enabled) and redrew the highlight, in b5860bf7b.

• Both images now show the DOM-rendered node: collapse chevron in the header, Nodes 2.0 sockets, no legacy title band / divider.
• The box on the newly added image2 input is now derived from the input row geometry (socket dot + label + 5 px of air) instead of being placed by eye, so it encloses the whole row and no longer cuts through the label.
• Stroke is the standard 3 px #F2FF59 outline, no glow, rounded corners: the previous one was a ~0.5 px hairline.

Captured on ComfyUI 0.34.0 / frontend 1.51.9, English UI, canvas zoom 1.5, so both files are 1556 px wide (previously 1908 px) with identical framing; autogrow-1 1556x712, autogrow-2 1556x832. No text or file-name changes, so the .mdx sources and translations are untouched.
