feat: landing page redesign

- New hero headline "Turn any video into a watch party" with animated
  gradient highlight, sharper subtitle and quiet trust line under the CTAs
- Changelog badge redesigned as the koala's speech bubble (version and
  release date baked in at build time, no version.json fetch anymore)
- Light/dark theme toggle in the header (dark default, pre-paint via
  lang-init, full light theme across sections)
- Use cases and "Why KoalaSync" merged into one section with the three
  strongest feature tiles; question-mark koala moved to the FAQ
- FAQ and self-hosting setup collapsed by default via shared
  section-collapse component (hash deep links auto-open them)
- Compat/juggler section more compact
- og:image switched to the 1280x640 repository OpenGraph card (landing
  and join page), generated during build
- "watch party" keyword added to meta title/description in all 15 locales
- All em-dashes removed from user-facing copy
