Add 8 tests that would have caught the pipeline bug where custom-route
tools (remove-background, upscale, ocr, etc.) were shown in the
pipeline picker but failed silently when executed.
New tests:
- GET /api/v1/pipeline/tools returns factory-registered tool IDs
- Verify resize, crop, convert, compress, rotate are included
- Verify remove-background, upscale, ocr, blur-faces, erase-object,
info, collage, compare are excluded
- Pipeline execution returns 400 for each custom-route tool
The integration test cleanup was deleting the shared temp directory
(rmSync on dirname(DB_PATH)), which causes SQLITE_IOERR_FSTAT in
other test files that still reference the same database. The temp
directory uses a random UUID under /tmp and is cleaned up by the OS.
Add feature flag support to skip disabled/experimental tools at startup
by reading disabledTools and enableExperimentalTools from the settings
table. Refactor cleanup.ts to read tempFileMaxAgeHours from DB settings
(with env var fallback) and respect the startupCleanup setting.
Extract EXIF auto-orientation logic into a shared auto-orient module
used by both single-tool and batch routes. This ensures camera photos
display correctly after processing regardless of entry point.
Also expands e2e and integration tests significantly.
