GraphHopper now loads its routing rules from `backend/custom_models/beebeebike.json` (added in #72), but neither the prod compose nor the CD sync step were updated to ship that directory: - compose.prod.yml didn't bind-mount custom_models, so the GH container couldn't see the file even when present on the host. - The CD `Sync runtime config` step only scp'd compose.prod.yml and graphhopper_config.yml, so the custom model never reached helena. Symptom in prod after merging #72: GH crash-looped with `/custom_models/beebeebike.json (No such file or directory)`. This was deployed manually to unblock; the change here is what the next CD run needs to keep prod consistent.

Superseded by #75 — moves custom_models into a thin GH image so host-side bind mount + scp sync are no longer needed. |

Replace the host-side bind mount of `backend/custom_models/` with a custom GH image that COPYs the dir at build time. CD builds and pushes `ghcr.io/cafca/beebeebike-graphhopper:latest` alongside the backend image; `compose.prod.yml` pulls it. Routing rules now ship atomically with `docker compose pull`, no scp dance, no separate sync path. CD also gains a post-deploy probe: if the freshly-started GH container logs `Profile 'X' does not match` (i.e. the new image carries different priority/speed/distance_influence rules from what the cached graph was baked against), CD wipes `data/osm/berlin/graphhopper` and reimports. Cache is preserved across normal backend-only deploys. Supersedes #73 — the host-side custom_models scp + bind mount approach becomes unnecessary once the file lives inside the image that reads it.

Summary
After merging #72, prod GraphHopper crash-looped with:
Two missing pieces caused this:
compose.prod.ymlhad no bind mount for the custom models directory, so even when the file was present on disk, the GH container couldn't see it..github/workflows/cd.yml's "Sync runtime config" step only scp'dcompose.prod.ymlandbackend/graphhopper_config.yml;backend/custom_models/*never reached helena.This PR fixes both so the next CD run keeps prod consistent. Already deployed manually to unblock; this just codifies the fix.
Notes
Test plan
backend/custom_models/*and prod GH stays healthy through the deploy.
