ci: add automated PR validation pipeline + fix regressions

NEW: Gitea Actions CI pipeline (.gitea/workflows/pr-pipeline.yaml)
- Stage 1 (validate): YAML frontmatter validation for all .prose.md files
- Stage 2 (lint): Structural checks + regression detection
  * /grafana/ nginx route (reverted 2026-07-02)
  * Stale CT IDs (122→112, no 123)
  * Verified: .19/.122/.123 = correct bridge IPs
- Stage 3 (ai-review): LiteLLM-powered diff review against ground truth
- Stage 4 (auto-merge): Gate — safe to merge when all green

NEW: scripts/prose-lint.sh — contract structure + regression checker
NEW: scripts/prose-ai-review.sh — AI review via syslog-auto model

FIXES FOUND BY LINT:
- gpu-fleet.prose.md: removed /grafana/ from nginx routing diagram
- gpu-fleet.prose.md: removed /grafana/ from config file description
- infrastructure-control.prose.md: CT 122→112 in topology diagram
- scripts/prose-lint.sh: updated to not flag .19 (verified correct IP)

+## INFRASTRUCTURE GROUND TRUTH
+
+The infrastructure-control.prose.md contract is the canonical reference for the cluster topology:
+
+**Proxmox Cluster "Tabiri" (5 nodes):**
+- amdpve (192.168.68.15): abiba, kagentz, tanko, tdunna, baggy, scottdenya
+- minipve (192.168.68.12): authentik, gitea, mumuni, syslog-api, jitsi
+- storepve (192.168.68.6): docker-vm, ra-h-os, PBS, media, zulip
+- acerpve (192.168.68.9): llm-gpu, adguard
+- ocupve (192.168.68.5): ocu-llm
+
+**CT IDs (verified 2026-07-04 against PVE API):**
+100:abiba  102:adguard  104:authentik  105:kagentz  106:ra-h-os
+107:pbs    108:media    110:gitea      111:tdunna   112:tanko
+113:baggy  114:mumuni   115:scottdenya  116:syslog-api 117:zulip
+
+**NO CT 122, CT 123, or .19 exist in the cluster.**
+
+**CRITICAL RULES (never regress):**
+1. NO /grafana/ nginx route — it was tried and reverted on 2026-07-02. Grafana is direct LAN at :3001.
+2. NO .19 IP — Zulip is CT 117 on storepve.
+3. NO CT 122/123 — Tanko=CT 112, Mumuni=CT 114.
+4. Strix Halo :8080 is FIREWALLED to .116 only — cannot be probed from abiba (.24).
+5. abiba-zulip PM2 process is DECOMMISSIONED (2026-07-04) — abiba uses Telegram only.
+
+**Docker on CT 116 (8 containers):**
+harness-litellm, harness-router, harness-nginx, harness-postgres, 
+harness-redis, harness-dashboard, harness-grafana, harness-prometheus
+
+## DIFF TO REVIEW
+
+$DIFF
+
+## REVIEW INSTRUCTIONS
+
+Check the diff for:
+1. Does it introduce any contradictions with the ground truth above?
+2. Does it re-introduce any previously-fixed issues (Grafana /grafana/ route, stale CT IDs, .19)?
+3. Are any IPs or hostnames wrong?
+4. Does the frontmatter have valid kind, name, and description fields?
+5. Is anything inconsistent with other contracts in the repo?
+
+Respond with a concise review in this format:
+
+**Verdict:** APPROVED / CHANGES_REQUESTED
+
+**Issues found:**
+- [issue 1]
+- [issue 2]
