mac-mini wired to LAN: update IPs and revert WiFi moonlight/sunshine configs

Browse Source 
- mac-mini: lan_ip 192.168.8.174 → 192.168.178.182 (wired en0)
- ludo-mini: add lan_ip (192.168.178.181) and ssh user (dtoro)
- Investigation doc: mark Ethernet wiring resolved, add wired-era settings
- Moonlight: bitrate 60→80 Mbps, framepacing off
- Sunshine: bitrate 40→80 Mbps, fec 2→5%, packetsize 1024→1316

### ludo-mini — Sunshine (via SSH)
| Setting | Before | After | Rationale |
|---------|--------|-------|-----------|
| bitrate | 80 Mbps | 40 Mbps | Match Moonlight's reduced bitrate ceiling |
| fec_percentage | 5 | 2 | Less forward-error-correction overhead over WiFi |
| packetsize | (default) | 1024 | Smaller packets = less WiFi retransmit cost |
| Setting | WiFi value | Wired value | Rationale |
||---------|-----------|-------------|-----------|
|| bitrate | 40 Mbps | 80 Mbps | Wired can handle full bandwidth |
|| fec_percentage | 2 | 5 | Restored to default — wired has no dropout concern |

## Resolution
### 2026-06-04 — mac-mini wired to LAN
mac-mini plugged into Ethernet (en0, 192.168.178.182). This definitively resolves the WiFi jitter that caused streaming instability. All WiFi-era conservative settings reverted to appropriate wired values on both ends.
## Open questions
1. **Ethernet wiring** — mac-mini has an active en0 port. Plugging it into the same switch/router as ludo-mini would eliminate WiFi jitter entirely. This is the definitive fix.
~~1. **Ethernet wiring** — mac-mini has an active en0 port. Plugging it into the same switch/router as ludo-mini would eliminate WiFi jitter entirely. This is the definitive fix.~~ **RESOLVED** — mac-mini now wired via en0.
2. **WiFi alternatives** — If wiring is impractical, a WiFi 6 (802.11ax) USB adapter or Thunderbolt-to-Ethernet adapter would help, but wired Ethernet is the only reliable solution for game streaming.
3. **Netbird route** — `192.168.8.0/24` is routed over Netbird `utun100`. If Moonlight ever falls back to that subnet (ludo-mini's 192.168.8.133 LAN IP), traffic tunnels unnecessarily. Moonlight correctly uses 192.168.178.181, so this is not currently an issue.
## Changelog
### 2026-06-03 — Initial investigation and mitigations
- Diagnosed WiFi jitter as root cause of unstable Sunshine/Moonlight streaming
- Applied Moonlight bitrate reduction (57→25 Mbps), frame pacing, fps fix
- Applied Sunshine bitrate reduction (80→40 Mbps), fec_percentage (5→2), packetsize (1024)
- Documented findings and open questions
### 2026-06-04 — mac-mini wired to LAN, configs reverted from WiFi mitigations
- mac-mini connected via en0 (wired Ethernet, 192.168.178.182), WiFi mitigations no longer needed
- Moonlight: bitrate 60→80 Mbps, framepacing disabled
- Sunshine: bitrate 40→80 Mbps, fec_percentage 2→5, packetsize restored to default (1316)
- First root cause in investigation (Open questions #1) resolved
