imick-io 010389903d feat(website): sitewide announcement banner (#13481)
## Summary

Adds a **sitewide announcement banner** to the website, rendered above
the navbar on every page. It has a two-layer visibility model:

- **Build-time gate** — a pure, unit-tested `evaluateBannerVisibility()`
decides whether the banner mounts at all (active flag + optional date
window + locale/section targeting), driven by a typed config
(`src/config/banner.ts`). No CMS; copy resolves through i18n.
- **Client-side dismissal** — persisted in `localStorage`, keyed by a
**content hash** so editing the copy re-shows the banner (per-locale, so
an en edit doesn't re-show it for zh-CN).

Current content points the CTA at **Comfy MCP** (`/mcp`).

## Highlights

- **Full-width branded bar** above a now-`sticky` navbar; reuses the
design system (`Button`, gradient tokens, new reusable `IconButton`).
- **Flash-free** on load: an inline pre-hydration script hides an
already-dismissed banner before paint (no pop-in, no layout shift);
`close()` sets the same signal after the leave animation to stay
flash-free across ClientRouter navigations.
- **Open/close transition**: grid-rows height collapse + fade,
respecting `prefers-reduced-motion`.
- **i18n**: copy in `en` + `zh-CN`.

## Where to edit later

- **Copy**: `apps/website/src/i18n/translations.ts` →
`launches.banner.text` / `launches.banner.cta`
- **Link / on-off / dates / targeting**:
`apps/website/src/config/banner.ts` (`bannerConfig`)

## Notes

- On a static site the `startsAt`/`endsAt` window is evaluated at
**build time** (documented in `banner.ts`).
- Changing the copy or link changes the content hash, so
previously-dismissed visitors will see the banner again — by design.

## Test plan

- `pnpm test:unit` — evaluator + version-hash unit tests pass.
- `pnpm typecheck` + lint clean.
- On the preview: banner shows on `/`, `/launches`, and a `zh-CN` page;
CTA -> `/mcp`; dismiss animates and stays dismissed on reload (no
flash); reduced-motion disables the animation.
