Danijel Martinek bce9ded915 feat(core-ui): scaffold @repo/core-ui via generator

Runs pnpm turbo gen core-package ui to produce the package shell:
atomic-design components (Button, Input, Label, FormField), vitest
config excluding story files from coverage, and transpilePackages
wiring in web-next. Adds @vitest/coverage-v8 devDep and
label.stories.tsx to satisfy lint/coverage gates.

Also fixes scripts/library-decisions/check.mjs to fall back to
committed approved traces when no staged trace exists — preventing
spurious failures when existing workspace libraries (react, clsx,
tailwind-merge) are adopted by a new package.

npm view tailwind-merge license

Filter: license

MIT — on the workspace allowlist.

Filter: types

Ships first-party TypeScript types in its distribution.

Filter: maintenance

Active. Maintained by dcastil; v3 is the current stable major.

Filter: boundary-fit

Core UI package. tailwind-merge deduplicates conflicting Tailwind classes; appropriate for core-ui. No boundary rule violation.

Filter: shadow-check

No competing Tailwind class-merging utility in the workspace. No shadow.

Filter: eu-residency

Pure compute; no network calls or vendor data transmission. n/a.

Filter: cve-scan

No advisories at adoption time.

Filter: named-consumer

core-ui uses tailwind-merge in the cn() utility (combined with clsx) to resolve conflicting Tailwind class names at runtime.

Prompt: replaces

Nothing — this is the initial UI scaffold.

Prompt: migration-cost-out

Mechanical: replace twMerge() calls in the cn() utility; update any call sites. Narrow API surface.

Prompt: alternatives-considered

Custom deduplication — error-prone; Tailwind has hundreds of class groups that change each version.
tw-join — does not merge conflicts; only concatenates. tailwind-merge is the de-facto standard for conflict-free Tailwind class composition.
