Use vipsthumbnail as the primary still-image path for both thumbnails and previews (shared serveGenerated), falling back to the pure-Go imaging pipeline when vips isn't on PATH. vips shrinks on load (e.g. JPEG DCT scaling), so a 200+ Mpx photo is resized in a fraction of the memory and CPU of a full in-process decode and no longer exceeds the decode cap — the source that previously got only a placeholder now gets a real thumbnail and preview. The output JPEG is written straight to the cache (atomic temp→rename), fit within the target box and never upscaled. The in-process pixel cap now guards only the pure-Go fallback.
