feat: Media Agent Blocco A+B + Calendar Agent fix

Blocco A — Jellyfin Playback Agent (AyrKWvboPldzZPsM):
- Webhook PlaybackStart/Stop → behavioral_context + agent_messages
- Fix: JSON.parse Jellyfin body, SSL Patroni, Postgres queryParams inline

Blocco B1 — Media Library Sync (o3uM1xDLTAKw4D6E):
- Weekly cron: Radarr+Sonarr → GPT-4.1 → memory_facts + Qdrant
- Qdrant collection media_preferences creata (768-dim nomic-embed-text)

Blocco B2 — Jellyfin Watch History Sync (K07e4PPANXDkmQsr):
- Daily cron: Jellyfin history (90d) → GPT-4.1 → memory_facts
- Jellyfin API token Pompeo creato via admin auth

Calendar Agent fix (4ZIEGck9n4l5qaDt):
- Cleanup: filter(i=>i.json.uid) per evitare undefined non quotato in SQL
- Salva Evento: rimosso updated_at=NOW() (colonna non esistente)

+## [2026-03-21] Media Agent — Blocco A+B completo + Calendar Agent fix
+
+### Nuovi workflow n8n
+
+#### 🎬 Jellyfin Playback Agent [Webhook] (`AyrKWvboPldzZPsM`) — Blocco A ✅
+
+Webhook in real-time che intercetta PlaybackStart / PlaybackStop da Jellyfin.
+
+**Bug fix applicati (debugging session):**
+1. **Webhook path** — `webhookId` deve essere top-level nel nodo JSON (non in `parameters`), altrimenti n8n v2.5.2 in queue mode registra path come `{workflowId}/{nodeName}/{path}` non raggiungibile
+2. **SSL Patroni** — `NODE_TLS_REJECT_UNAUTHORIZED=0` aggiunto a `n8n-app` e `n8n-app-worker` deployments (Patroni forza `hostssl`)
+3. **Postgres queryParams** — Postgres node v2 non valuta correttamente `$json.*` in `queryParams` → migrato a SQL inline con `{{ $json.field }}`
+4. **Jellyfin body format** — il plugin Webhook di Jellyfin invia il body come stringa JSON embedded (`$json.body = '{"ServerId":...}'`) → aggiunto `JSON.parse()` nel Code node
+5. **Jellyfin field names** — campi reali: `Name` (non `ItemName`), `DeviceName`/`Client`, `UserId` (senza trattini)
+
+**Comportamento verificato:**
+- PlaybackStart → INSERT `behavioral_context` (`do_not_disturb=true`)
+- PlaybackStop (chiusura player) → UPDATE `end_at`, `do_not_disturb=false`
+- `agent_messages` → `▶️ Ghost in the Shell (Chrome - PC)` / `⏹️ …`
+- La pausa NON triggerizza PlaybackStop (solo la chiusura del player lo fa)
+
+---
+
+#### 🎬 Media Library Sync [Schedule] (`o3uM1xDLTAKw4D6E`) — Blocco B1 ✅
+
+Weekly cron (domenica 03:00). Radarr + Sonarr → GPT-4.1 → Postgres + Qdrant.
+
+- Fetch Radarr `/radarr/api/v3/movie` + Sonarr `/sonarr/api/v3/series`
+- Merge e normalizzazione: `{type, title, year, genres, status, source, source_id}`
+- GPT-4.1 (GitHub Copilot): analisi taste → `{top_genres, preferred_types, library_stats, taste_summary, notable_patterns}`
+- Postgres upsert: `memory_facts` (source=`media_library`, source_ref=`media_preferences_summary`, expires +7d)
+- Loop per ogni titolo: Ollama `nomic-embed-text` (768-dim) → Qdrant `media_preferences` (Cosine)
+
+**Qdrant collection `media_preferences` creata** (PUT `/collections/media_preferences`, vettori 768-dim Cosine).
+
+---
+
+#### 🎞️ Jellyfin Watch History Sync [Schedule] (`K07e4PPANXDkmQsr`) — Blocco B2 ✅
+
+Daily cron (04:00). Jellyfin history → GPT-4.1 → Postgres.
+
+- Fetch `/Users/{martin_id}/Items` ultimi 100 played, filtro PlayCount > 0 e last 90 days
+- GPT-4.1: `{recent_favorites, preferred_genres, watch_patterns, completion_rate, notes}`
+- Postgres upsert: `memory_facts` (source=`jellyfin`, source_ref=`watch_history_summary`, expires +30d)
+
+**Jellyfin API token** (`d153606c1ca54574a20d2b40fcf1b02e`) creato via `POST /Auth/Keys?app=Pompeo` con sessione admin (`admin` / `__Montecarlo00!`).
+
+---
+
+### Fix workflow esistenti
+
+#### 📅 Calendar Agent (`4ZIEGck9n4l5qaDt`) — 2 bug fix
+
+1. **`🗑️ Cleanup Cancellati` — `column "undefined" does not exist`**: l'espressione `.map(i => "'" + i.json.uid.replace(...)+"'")` chiamava `.replace()` su `undefined` quando Parse GPT restituisce `{skip:true}` → l'intera espressione `{{ }}` valutava a `undefined` (non quotato) → PostgreSQL interpretava `undefined` come identificatore. Fix: aggiunto `.filter(i => i.json.uid)` prima del `.map()` + `String()` wrapper.
+2. **`💾 Postgres - Salva Evento` — `updated_at`**: ON CONFLICT UPDATE includeva `updated_at = NOW()` ma la colonna non esiste in `memory_facts`. Rimosso.
