feat(github-runner): harden Linux runner fleet

Shared.Pos build fails on non-root runner (setup-dotnet /usr/share/dotnet denied); churning runner drove HighCPU on rke2-agent2. Re-enable in the Sprint 30+ Cx-1 Linux-runner-fleet lane (DOTNET_INSTALL_DIR on pod env).

+# fc-redis — SignalR backplane for cross-product event bus
+#
+# Lands per Q-SO-1 resolution (2026-05-11 PM): SignalR backplane in Phase A,
+# not Phase C as originally drafted. Operator directive: "Redis can be
+# deployed just fine as it's another FlowerCore technology we'll want to
+# manage."
+#
+# Phase A scope (this file):
+#   - Single Redis 7.x Alpine pod
+#   - 1Gi Longhorn RWO PVC for AOF persistence
+#   - ClusterIP Service at `redis.fc-redis.svc.cluster.local:6379`
+#   - No AUTH (in-cluster only; not exposed externally)
+#   - No IngressRoute (backplane is server-to-server only)
+#
+# Consumers (Phase A IMPL across FC services):
+#   - FlowerCore.Signage.Web (OpsConsoleHub)
+#   - FlowerCore.Scoreboard.Web (ScoreboardHub)
+#   - FlowerCore.SignalControl.Web
+#   - FlowerCore.DMS.Web
+#   - Any other product joining the cross-product event bus
+#
+# Each consumer adds:
+#   services.AddSignalR()
+#           .AddStackExchangeRedis(
+#               "redis.fc-redis.svc.cluster.local:6379",
+#               opts => opts.Configuration.ChannelPrefix =
+#                   StackExchange.Redis.RedisChannel.Literal("fc-opsconsole"));
+#
+# Phase B / C follow-ons (out of scope here):
+#   - Redis Sentinel for HA (3-node)
+#   - AUTH password from 1Password Connect (rotate via /rotate-password)
+#   - redis_exporter sidecar for Prometheus scrape
+#   - Network policies restricting which namespaces can dial 6379
+#
+# Design: docs/signage/operations-console-phase-2-design.md §3.5
+# Decision: Q-SO-1 (RESOLVED 2026-05-11 PM)
+# Memory: feedback_blooming_ui_pattern_no_iframes

+Apple TV signage is a sealed appliance running the `FlowerCore.Signage.Agent.AppleTv` tvOS app per ADR-134.
+
+This ApplicationSet entry is documentation and inventory metadata only. It intentionally creates no `Deployment`, `Service`, or `Pod`.
+
+The Apple TV app connects outbound to existing FC.Signage.Web surfaces:
+
+- `https://signage.iamworkin.lan/hub/signage` for SignalR live status.
+- `GET /api/v1/nodes/{nodeId}/state` for the 30 second polling fallback.
+- `POST /api/v1/nodes/register` and `POST /api/v1/nodes/{nodeId}/enroll` for pairing and mTLS enrollment.
+- `POST /api/v1/nodes/{nodeId}/heartbeat` for metrics, current content identity, and local audit excerpts.
+
+Distribution is via Apple Developer Enterprise Program or TestFlight plus FC.Distribution / UpdateCenter publishing once Apple credentials are available.

+# FlowerCore Signage Pi Player
+
+Phase 1 Raspberry Pi signage player packaging for Chromium kiosk deployments.
+This bundle is intentionally air-gap friendly: systemd units, shell scripts,
+udev rules, and Chromium managed policy are all checked into the repo and are
+installed by `FlowerCore.Puppet`.
+
+## Scope
+
+- Bootstrap a stable node identity and mTLS client certificate.
+- Launch Chromium in kiosk mode against `FC.Signage.Web` player routes.
+- Restart the kiosk on HDMI hotplug.
+- Renew mTLS certificates daily when fewer than 30 days remain.
+- Detect display capabilities at boot, daily, and on HDMI hotplug.
+
+Phase 2 native Avalonia rendering is documented separately in Notes and remains
+deferred.

+# GitHub Runner Fleet
+
+ArgoCD owns `apps/github-runner/github-runner.yaml`. Do not patch live runner
+Deployments with `kubectl`; update this manifest and let ArgoCD reconcile.
+
+## Runner Shape
+
+All repo-scoped Linux runners use:
+
+- `ACCESS_TOKEN` from the `github-runner-token` Secret
+- `RUN_AS_ROOT=false`
+- `EPHEMERAL=true`
+- `LABELS=self-hosted,linux,fc-build-linux`
+- writable non-root paths under `/home/runner` for .NET, NuGet, XDG cache, and
+  Actions tool cache
+
+`github-runner` for `FlowerCore.Common` is single-replica because it retains the
+original Longhorn ReadWriteOnce NuGet PVC. `github-runner-sharedpos` and the top
+Linux-cost repo runners use two replicas with per-pod `emptyDir` caches. That is
+the safe backlog-drain strategy: no two pods share one RWO PVC.
+
+## Post-Merge Proof
+
+After the PR is merged and ArgoCD syncs, verify the runner fleet:
+
+```bash
+kubectl -n github-runner get deploy,pods,pvc
+```
+
+Verify GitHub registration for the repo-scoped runners:
+
+```bash
+for repo in FlowerCore.Common FlowerCore.Shared.Pos FlowerCore.Puppet FlowerCore.Signage \
+            FlowerCore.DMS FlowerCore.Telephony FlowerCore.Print.Web FlowerCore.Chat \
+            FlowerCore.MySQL FlowerCore.Kiosk.Linux; do
+  echo "=== $repo ==="
+  gh api "/repos/astoltz/$repo/actions/runners" \
+    --jq '.runners[] | select(.labels[].name == "fc-build-linux") | {name,status,busy,labels:[.labels[].name]}'
+done
+```
+
+Shared.Pos publish proof after the runner pod is online:
+
+```bash
+gh run list --repo astoltz/FlowerCore.Shared.Pos \
+  --workflow "Build, Test & Publish" --branch main --limit 5
+```
+
+If the latest run is still queued after runner registration, rerun the workflow
+from GitHub Actions and verify it lands on an `rke2-linux-*` runner.
+
+## Failure Notes
+
+- `actions/setup-dotnet` permission error at `/usr/share/dotnet`: check that
+  `DOTNET_INSTALL_DIR=/home/runner/.dotnet` and related cache env vars are
+  present on the runner pod.
+- `404` during runner registration: the fine-grained PAT is valid but missing
+  repository access for that repo. Add the repo to the PAT access list; the PAT
+  value does not change.
+- `Multi-Attach` volume error: only the Common runner uses a RWO PVC and it must
+  stay single-replica. New multi-replica runners use `emptyDir`.
