gpu-fleet: July 8 optimization sweep — parallel 2 fleet-wide, 128K ctx on NVIDIA, LiteLLM timeout fixes

- All GPUs: --parallel 1 → 2 (6 concurrent slots, was 3)
- .8 RTX 3090: ctx 256K→128K, VRAM 96%→83%, turbo4 KV cache
- .110 RTX 5070: ctx 256K→128K, ubatch 4096→512 (was inverted), VRAM 90%→77%, q4_0 KV
- .15 Strix Halo: parallel 1→2, 256K ctx (41GB free), q8_0 KV, AMD metrics via /sys/class/drm
- LiteLLM: gemma timeout 25→120s, qwen timeout 40→90s, syslog-auto (qwen) 40→90s
- Agent configs: context_length 262144 for syslog-auto, 131072 for direct qwen/gemma
- Updated health-check operation, agent config implications, benchmark table (fixed model↔GPU mapping)

+### For pi Agents (Tdunna)

+Tdunna (CT111) runs pi 0.80.3 via PM2 with the Zulip extension (router-worker architecture).
+Config files: `~/.pi/agent/models.json`, `~/.pi/agent/settings.json`.
+
+**models.json** — Must only list models authorized for the agent's LiteLLM key:
+```json
+{
+  "providers": {
+    "syslog-harness": {
+      "baseUrl": "http://192.168.68.116/v1",
+      "api": "openai-completions",

+        { "id": "gemma-4-12b" }
+      ]
+    }
+  }
+}
+```
+
+**settings.json** — Always use `syslog-auto` as default:
+```json
+{
+  "defaultProvider": "syslog-harness",
+  "defaultModel": "syslog-auto"
+}
+```
+
+**Validation**: Verify models match LiteLLM's authorized list:
+```bash
+curl -s http://192.168.68.116:4000/v1/models \
+  -H "Authorization: Bearer $(grep apiKey ~/.pi/agent/models.json | head -1 | cut -d'"' -f4)" \
+  | jq '.data[].id'
+```
+
+**Stuck worker detection**: In PM2 logs, `workers=[<id>:busy:N]` with growing N indicates
+a stuck worker (model error, no `agent_end` emitted). Fix: correct models.json, delete
+stale sessions from `~/.pi/agent/sessions/zulip/`, restart PM2.

+**Service**: `pm2 restart koby-zulip`, health at `:9201/health`.
