feat: replace HTML export with SvelteKit viewer
Replace the minijinja-based HTML export with a full SvelteKit static viewer app. The new export produces a ZIP with: - Pre-built viewer assets (index.html + JS/CSS bundle) - data.json with all posts, comments, tags, and like counts - Processed media: 400px thumbnails for grid, full images (2000px cap if >5MB), video thumbnails via ffmpeg Remove minijinja dependency, add include_dir to embed viewer assets at compile time. Update Dockerfile to copy static/ for builds. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
