## Summary
Weekly "make one non-local container local" pickup: immich-ringtail still pulled `docker.io/valkey/valkey:8.1.6` because the existing `containers/valkey/container.py` build was arm64-only.
- Adds `containers/valkey/default.nix` — nix-built amd64 valkey image, packaged by the ringtail nix-container-builder runner using `pkgs.dockerTools.buildLayeredImage`. Mirrors the existing `containers/authentik-redis/default.nix` pattern.
- `containers/valkey/container.py` keeps building the Alpine arm64 image for paperless on indri. Bumped both builds to upstream valkey 8.1.7 (Alpine 3.22 now ships `8.1.7-r0`; nixpkgs has 8.1.7).
- Splits `VERSION` (upstream app) from `ALPINE_PIN` (apk pin) in `container.py` so both build files can declare the same upstream version and pass `container-version-check`.
- Updates `service-versions.yaml`: current-version 8.1.7, refreshed last-reviewed, upstream-source now points at the canonical valkey-io releases page.
- Switches kustomizations:
- `immich-ringtail/kustomization.yaml`: `docker.io/valkey/valkey:8.1.6` → `registry.ops.eblu.me/blumeops/valkey:v8.1.7-02859c5-nix`, comment updated.
- `paperless/kustomization.yaml`: `v8.1.6-r0-fabca04` → `v8.1.7-02859c5`.
## Build
build-container run #563 — both jobs succeeded after a transient runner crash on the first dispatch (#562 build-nix), which surfaced two separate bugs that landed in a separate C0 on main:
- `runner-logs` silently returned 0 with no output when the log file didn't exist on indri
- `ssh indri` swallowing remote exit codes (fish login shell), which the wrapper now works around via a stdout marker
## Test plan
- [ ] `argocd app set immich-ringtail --revision valkey-nix && argocd app sync immich-ringtail`
- [ ] `argocd app set paperless --revision valkey-nix && argocd app sync paperless`
- [ ] Both valkey pods come Ready and start serving on :6379
- [ ] Immich app + paperless can read/write their respective cache
- [ ] After merge: rebuild from squashed main commit + update kustomization tags (squash-tag follow-up)
