chore(deps): remove unused devDependencies (colors, ts-node, stylelint-config-standard, chromatic)

[droshev]

Removes 4 packages that are no longer used in the codebase:

Package	Reason
colors	No imports or requires anywhere. Added in #3087 (webpack 5 / Windows compat migration, Jan 2022) — the code that needed it is long gone.
ts-node	Only reference was the transform-stories script pointing to stories-transformer.ts, which doesn't exist. Config block in tsconfig.base.json also removed.
stylelint-config-standard	Redundant — already a transitive dependency of stylelint-config-standard-scss, which is what .stylelintrc.json actually extends.
chromatic	CI uses chromaui/action@v18.10.1, which bundles its own CLI. No npm script references the chromatic CLI. Not used locally either.

One from Claude:

[.github/actions/generate-conventional-release-notes/closest-version.mjs:3]
Issue: The git-semver-tags npm package is not unused — it is actively imported in this file:

import gitSemverTags from 'git-semver-tags';

The code calls it with the npm callback API (gitSemverTags({ tagPrefix: 'v', skipUnstable: false }, function(err, result) {...})). Removing the package will break the generate-conventional-release-notes GitHub Action at runtime.

The PR description states "The npm package is never imported" — this is incorrect. The custom helper at .github/actions/helpers/git-semver-tags.mjs uses a completely different API (positional args, synchronous, no callback, no tagPrefix option) and cannot be a drop-in substitute without also updating closest-version.mjs.

Fix: Either:

• Keep git-semver-tags in devDependencies, OR
• Update closest-version.mjs to use the custom helper's API before removing the package.
