Colby McHenry a72f22a6d3 feat(ui): scaffold the codegraph ui viewer as a Svelte 5 + Vite workspace (CG-40)
Adds `ui/` as an npm workspace (Svelte 5.56 + Vite 7, devDependencies only —
the engine's runtime dependencies are untouched) and chains its build into
`npm run build`, so the browser viewer ships inside `dist/` with everything
else: `build-bundle.sh` already copies `dist` wholesale and `pack-npm.sh`
packs that bundle.

Output is `dist/viewer/`, NOT `dist/ui/`: `src/ui/` is the engine's terminal
ui (shimmer progress + its worker) and tsc compiles it to `dist/ui/`, so
emitting there both deletes those modules — the CLI then dies at startup with
`Cannot find module '../ui/shimmer-progress'` — and would leave the static
server handing out compiled engine internals. The design spec is corrected to
match.

`scripts/check-ui-build.mjs` is the release guard: index.html must exist, be
non-trivial, and every local asset it references must be on disk, and the
compiled engine next door must still be intact. It runs after every UI build,
again in `build-bundle.sh` once the bundle stage has copied `dist`, and again
in `pack-npm.sh` once each archive is unpacked — so a broken viewer fails the
release instead of shipping a CLI that serves a 404.

`vite build` does not override an ambient NODE_ENV, so a shell or runner with
NODE_ENV=development silently shipped dev-mode Svelte (~13 kB of dev-only
runtime checks, warning in the user's console). The config now pins production
for `command === 'build'`; macOS and Windows ARM64 then emit byte-identical
bundle hashes.

The shell itself follows docs/design/codegraph-ui-design-spec.md §2–§3.1:
design tokens as CSS custom properties (light on bare `:root`, dark under both
`prefers-color-scheme` and `[data-theme="dark"]`), square corners, hairline
rules, one oxblood accent; top bar 48px / trail bar 34px / main; a hash router
over `#/s/<id>`, `#/file/<path>`, with `#/map` and `#/flow` reserved for phase
2. Fonts are vendored through @fontsource rather than fetched, so a local
reader works offline and never announces the project to a CDN.

Verified: clean `npm run build` from an empty dist on macOS and on the Windows
ARM64 VM (forward-slash asset URLs, CLI still starts, both assertion failure
modes exit 1); `dist/viewer` present in a real darwin-arm64 bundle and in the
packed npm platform package; shell geometry, tokens, all seven routes, both
themes and font loading checked in headless Chromium with no console errors;
`npm test` unaffected.
