chore(design-sync): add Reactive Resume UI sync inputs (#3216)

* chore(design-sync): add Reactive Resume UI sync inputs

Sync inputs for the claude.ai/design "Reactive Resume" project — the
@reactive-resume/ui design system (39 primary components).

- .design-sync/config.json — converter config (synth-entry, 202->39 card
  prune, overlay/grid cardMode overrides, cssEntry, tsconfig, buildCmd)
- .design-sync/build-css.mjs + tw-entry.css — compile Tailwind v4 globals.css
  to a self-contained stylesheet (inlined IBM Plex font), emit real .d.ts,
  and create the workspace self-symlink the converter needs
- .design-sync/previews/*.tsx — 39 authored preview compositions
- .design-sync/conventions.md — design-agent usage header (readmeHeader)
- .design-sync/NOTES.md — re-sync notes, gotchas, and risks
- packages/ui/tsconfig.emit.json — declaration emit for real prop contracts

Build artifacts (dist/types, .ds-compiled.css, ds-bundle, .cache) are gitignored.

* chore(knip): ignore .design-sync inputs and drop stale es-toolkit ignore

- Ignore .design-sync/** (design-sync tooling: build-css.mjs + authored
  previews are standalone, not part of the app import graph — knip --fix was
  deleting them and failing the autofix job).
- Remove es-toolkit from apps/server ignoreDependencies: it's now really used
  (apps/server/src/http/health.ts imports withTimeout), so the ignore is stale.
