fix: ship pm2-self-heal crash-loop guard + align gpu-dense docs to Qwen3.8-27B

- pm2-self-heal.sh: restart abiba-telegram when TEL_RESTARTS > 1000 even if 'online'
  (catches quiet crash-loops like the 10k-restarts spoton incident); alert includes count.
- pm2-self-heal.prose.md: document the crash-loop guard under Rule 2.
- gpu-fleet.prose.md / gpu-self-heal.prose.md: gpu-dense is Qwen3.8-27B-Uncensored-Q4_K_M
  (~16.8GB, alias qwen3.6-27B-code for LiteLLM routing), not SmartCode-Fable-5 (verified live
  on .8:8080 Aug 16).

+### Rule 2: Process Restarting Too Often (crash-loop guard)
+- **Detect**: `pm2 status` shows restarts > 30 (cumulative lifetime counter) **or** a
+  process reporting a restart count > 1000 while showing "online" (a crash-loop mask)
 - **Note**: PM2 counter never decrements; only full delete+re-add resets it
 - **Fix**: `pm2 delete <name> && pm2 start <ecosystem> --only <name>`
+- **Script guard (2026-08-16)**: `scripts/pm2-self-heal.sh` now restarts `abiba-telegram`
+  when `TEL_RESTARTS > 1000` even if the process reports "online" — catches a quiet
+  crash-loop that never toggles status to "stopped"/"errored" (e.g. the 10k-restarts
+  spoton incident). Alerts include the restart count.
 - **Escalate**: Only when restarts > 30 — alerts to Zulip DM
 - **Historical fix**: Previous cycles were caused by abiba-zulip extension's
   stuck detection (STUCK_THRESHOLD_MS was 30min, raised to 4h in v2).
