Redesign docs site: Astro landing page with fresh v1.0.0 screenshots (#50)

* v1.0.0: live diff preview, auto-growing AI input, polished Settings

Three feedback fixes + the 1.0 version bump.

- AI composer now auto-grows as you type multiple lines (up to a max, then
  scrolls), instead of a fixed single row that hid earlier lines.

- Per-change accept/reject now updates the preview live. During review the
  editor shows the full proposed text, but the preview should show "original +
  changes accepted so far". @codemirror/merge's acceptChunk folds an accepted
  change into its *original* document, so getOriginalDoc() is exactly that
  running result — we sync it to onChange on every review update. Accepting a
  single change now appears in the preview immediately (previously only
  "Accept all" did). "Reject all" resets fully (passes the original, so any
  individually-accepted changes are discarded too).

- Settings polish: redesigned toggle switches (larger, smoother, better
  contrast on every theme), font options now preview themselves in their own
  typeface with a kind label and check, font-size options show an "Aa" scale
  preview, and the editor toggles are grouped into one bordered list.

- Bump version to 1.0.0 across tauri.conf.json, package.json, Cargo.toml,
  Cargo.lock.

* Redesign docs site: Astro landing page with fresh v1.0.0 screenshots

Rebuild the GitHub Pages site (docs/) from a single static index.html into
an Astro + Tailwind v4 project with cinematic motion and brand colors.

Highlights:
- Sections: hero, trust bar, features bento, live editor showcase,
  interactive 4-theme switcher, power-user gallery, AI Agent inline-diff
  demo, download cards, FAQ (with schema), footer
- Replace stale/empty screenshots with 8 fresh 1920x1030 captures of the
  running v1.0.0 app (split view; math/chemistry/Mermaid; all four themes;
  command palette; file explorer). Fresh og.png for social previews.
- GSAP + ScrollTrigger + Lenis: smooth scroll, reveals, parallax, tilt
- Lucide icons throughout (no emoji); orange/cyan brand accents; aurora
- Responsive WebP via astro:assets; prefers-reduced-motion and no-JS safe

Deploy:
- Add .github/workflows/deploy-docs.yml to build docs/ and publish to
  GitHub Pages via Actions on push to main (docs/** paths).
- Requires one-time repo Settings -> Pages -> Source = "GitHub Actions".
