skills: split f3s into six focused sibling skills (index pattern)

Execute plans/f3s-skill-split-plan.md. Carve the oversized f3s skill into six
f3s-prefixed siblings so each loads on its own triggers, and slim f3s to a hub
(38 reference files -> 10; 119 -> 73 lines):

- f3s-storage       ZFS/zrepl/CARP/NFS-stunnel, nfs-mount-monitor, backups
- f3s-k3s           cluster install, off-LAN access, ingress, etcd, r-node Rex
- f3s-observability Prometheus/Alloy/Loki/Tempo, FreeBSD node_exporter
- f3s-workloads     Immich, Garage, Player, yChat, goprecords/uptimed
- f3s-raspberry-pi  pi0/pi1 NetBSD static site, pi2/pi3 Pi-hole/LAN DNS
- f3s-dtail         dserver deployment/ops (SSH 2222)

f3s hub keeps the master Host-IP table, physical hosts, bhyve, WireGuard mesh,
and off-LAN access as the canonical inward-pointing context, plus a Related
skills block. Applies skill-maintenance best practices: fixes the three inlined
SKILL.md duplications (Pi/webserver, DTail) by moving prose to one canonical home
and keeping each new SKILL.md a slim index that points to its references rather
than re-inlining them. All cross-skill links rewritten to ../../<skill>/references/
form (incl. inbound links from pkgrepo and rocky-vm-setup, and two pre-existing
broken links); verified all 112 relative links resolve.

+name: f3s-workloads
+description: Reference skill for the application workloads running on the f3s homelab, Immich (photos), Garage (S3), the Player service, yChat (legacy C++ chat), and goprecords/uptimed uploads. Covers image build/push, Helm charts, ArgoCD sync, NFS PV/PVC wiring, edge domain routing, and per-app troubleshooting. Use when deploying, updating, or debugging a specific homelab application. Part of the f3s homelab skill family (hub, [`f3s`](../f3s/SKILL.md)).
+---
+
+# f3s Workloads
+
+The application workloads hosted on the f3s k3s cluster. Each app has its own
+reference with image build/push steps, Helm chart path, ArgoCD wiring, and NFS
+PV/PVC notes.
+
+## When to Use
+
+- Deploying, updating, or debugging one of the hosted homelab applications below
+- Questions about a specific app's image build/push, Helm chart, ArgoCD sync, or storage wiring
+- For the cluster these run on, see [`f3s-k3s`](../f3s-k3s/SKILL.md); for the NFS/PV storage layer, [`f3s-storage`](../f3s-storage/SKILL.md); for hosts/IPs, the [`f3s`](../f3s/SKILL.md) hub.
