docs: remove TrueNAS references, make volume paths platform agnostic

- compose.yml: generic /path/to/winnow/... placeholder paths
- docs/setup.md: replace TrueNAS section with generic GPU passthrough guide
- docs/faq.md: remove platform-specific path example
- README.md: soften crop quality disclaimer, remove TrueNAS compose note
- CHANGELOG.md: scrub TrueNAS mentions from release notes

-Yes — the `compose.yml` uses standard Docker volume mounts. The TrueNAS paths in the example (`/mnt/<pool>/...`) are just an example; replace them with whatever paths suit your setup.

+To enable GPU acceleration, include the `deploy` block in `compose.yml` (already present in the example) and ensure the NVIDIA container toolkit is installed on your host:
 
-```yaml
-volumes:

-GPU passthrough on TrueNAS requires the NVIDIA app to be installed from the TrueNAS catalog and the `deploy.resources.reservations.devices` block in `compose.yml` (already included).
+CPU mode works without any GPU setup — set `FORCE_CPU=true` to disable GPU explicitly.
