feat: Inline Hex Color Swatch rendering

まず、リンクされた hex-color-swatch-mod を確認し、command-code にある prompt-transform と feed response のエントリーポイントを特定します。入力アノテーションとレスポンス専用のスウォッチリストを、ネイティブな feed サポートにどのように統合すべきかを判断します。完了条件は、プロンプト内で16進カラーがインライン表示され、モデルの返信に対する feed の補助情報として重複のない色が表示され、元の返信が変更されないことです。

Feature Description

Ive buiit a mod to show hex color swatches in a prompt transform and also in some response output.

But, native feed support might be better as then the feed isn't generic and have to resort to a list summary of colors detected.

See: https://github.com/dthyresson/hex-color-swatch-mod

Use Case

Some examples ...

What it does

Two jobs, nothing else:

1. Inline swatches in your input

When you type a hex color like #fefefe, the prompt is transformed before
the model sees it — each color becomes a 2-wide solid box painted the actual
color, inline:

type:    use #fefefe and #0af for the theme
becomes: use ██ #fefefe and ██ #0af for the theme

The model sees the annotated color too, so it can reason about it.

2. Color list from model output

When the model's reply contains hex colors, the response is not
rewritten or echoed back. Instead, each unique color is extracted and rendered
as a compact list of swatches in the feed:

██ #fefefe ██ #3b82f6 ██ #00aaff

The model's original answer stays exactly as written — the list is just a
visual aid so you can see the colors at a glance.

Example prompts to try

Ask for colors in any of these ways and the mod will render a swatch list
from the reply:
