Update P5.1 with network connectivity finding

Browse source 
After approving macOS network access GUI prompt, minikube can now
reach sifaka. NFS still denied because sifaka exports don't include
Docker network (192.168.49.0/24). Updated Option B as viable alternative
if sifaka NFS exports are updated.

- Sifaka NFS exports `/volume1/torrents` to:
- `192.168.105.0/24` (old qemu2 VM network - no longer used)
- `100.64.0.0/10` (Tailscale CGNAT range)
- Minikube can resolve `sifaka` (192.168.1.203) but can't reach it (100% packet loss due to Docker network isolation)
- Network connectivity: ✅ Works after approving macOS network access GUI prompt
- NFS access: ❌ Denied (sifaka doesn't allow `192.168.49.0/24`)
**Option A: hostPath via Docker Desktop File Sharing** ⭐ RECOMMENDED
1. Mount sifaka NFS share on indri macOS: `mount -t nfs sifaka:/volume1/torrents /Volumes/torrents`

**Option B: Update sifaka NFS exports for Docker network**
1. Add `192.168.49.0/24` to sifaka's NFS exports
2. Pods mount NFS directly using kubernetes NFS volume type
**Option B: Update sifaka NFS exports for Docker network** ⭐ ALTERNATIVE
1. In Synology DSM: Control Panel → Shared Folder → torrents → Edit → NFS Permissions
2. Add `192.168.49.0/24` to allowed clients
3. Pods mount NFS directly using kubernetes NFS volume type
Pros:
- Simpler than Option A (no intermediate macOS mount)
- Direct path, better performance
- Network connectivity confirmed working (after macOS network access approval)
Cons:
- Requires sifaka configuration change (one-time)
- Docker network might change (though `192.168.49.x` seems stable for minikube)
- Requires sifaka configuration change
- NFS mount from inside container may have permission issues
Test command (after updating sifaka):
```bash
ssh indri 'minikube ssh "sudo mount -t nfs sifaka:/volume1/torrents /mnt/torrents && ls /mnt/torrents"'
```
**Option C: Tailscale sidecar for NFS access**
1. Pods include a Tailscale sidecar that joins the tailnet
