sharp's prebuilt Linux x64 binary requires SSE4.2 (x86-64-v2), causing a
SIGILL crash on older hardware (e.g. AMD A6-3420M). Replace with jimp, a
pure-JS image library with no native binaries. Also skip thumbnail generation
entirely when the Journey addon is disabled (the default), preventing the
issue for most installs regardless of the image library used.
Sharp throws on unsupported formats (HEIC, corrupt files, etc.) and the
error was propagated outside the try/catch, crashing the server. Moved the
mkdir + sharp pipeline inside the catch block so any failure returns null
and streamPhoto falls through to serving the original file.
Add thumbnailService that lazy-generates a WebP thumbnail (800px max, q80) on
first GET /api/photos/:id/thumbnail request using sharp. The generated file is
stored at uploads/journey/thumbs/<sha1>.webp and the path is persisted to
trek_photos.thumbnail_path so subsequent requests are served directly from disk.
Also populates width/height as a side-effect.
streamPhoto now branches on kind for local file_path rows — thumbnail requests
use the stored/generated thumb path; original requests (and fallback when thumb
generation fails) continue to serve the full file. Remote providers (Immich,
Synology) are unaffected.
