chore: bump version to 0.1.8

Expose per-crawler teaser settings on crawler cards and persist them through the admin API.\n\nWhen preview generation is disabled, crawler imports still create thumbnails and fingerprints while marking previews disabled and allowing migration without waiting for teaser files.\n\nPreserve the latest teaser setting after crawler runs so stale crawl state cannot overwrite a user toggle.
