George Powell 884bbe65c7 feat: add about page, sitemap, social links component, Apple sign-in
prompt on win screen, and layout/theme improvements

  ## New features

  - **About page** (`src/routes/about/`): New static about page rendered
    from `static/about.md` using the `marked` library (added as a
    dependency). Includes the project backstory content.

  - **XML sitemap** (`src/routes/sitemap.xml/`): Dynamic sitemap
    endpoint for SEO, registered in `static/robots.txt` via `Sitemap:`
    directive.

  - **Apple Sign In prompt on win screen** (`WinScreen.svelte`): When
    the game is won and the user is not logged in, a "Sign in to save
    your streak & see your stats" prompt with an Apple Sign In button is
    shown below the share card. Passes `anonymousId` so stats migrate on
    sign-up. Driven by new `isLoggedIn` and `anonymousId` props, passed
    from `+page.svelte`.

  ## Refactoring

  - **`SocialLinks` component**
    (`src/lib/components/SocialLinks.svelte`): Extracted the Bluesky,
    Twitter/X, and email social link icons from `Credits.svelte` into a
    reusable component. `Credits.svelte` now imports and renders
    `<SocialLinks />`.

  - **`ThemeToggle` component**
    (`src/lib/components/ThemeToggle.svelte`): New component for
    toggling light/dark mode, persisted to `localStorage`. Currently
    rendered but hidden (`hidden` class) in `+page.svelte` —
    infrastructure is in place for future use.

  ## Layout changes

  - **`+layout.svelte`**: Moved the page title/header (`<h1>` with
    `TitleAnimation`) and the gradient background wrapper from
    `+page.svelte` into the root layout, so it applies across all
    routes. Also removed the `browser` guard around the analytics script
    injection (it's
    already inside `onMount` which is client-only). Added `<meta
    name="description">`.

  - **`+page.svelte`**: Removed the title/header and gradient wrapper
    (now in layout). Minor formatting cleanup (reformatted `SearchInput`
    props, moved `currentDate` derived state earlier). `ThemeToggle`
    import swapped in place of `TitleAnimation` (which moved to layout).

  ## Styling

  - **`layout.css`**: Added `@custom-variant dark` for class-based dark
    mode toggling (supports `.dark` class on `<html>`). Added explicit
    `html.dark` / `html.light` rules alongside the existing
    `prefers-color-scheme` media query, so the `ThemeToggle` component
    can
    override the system preference. Added background transition
    animation.
