Add reusable LLM parser profiles with multi-event extract.

Support kind=llm profiles (instruction/schema), optional multi-event posts via #eN URLs, and recover stale running/queued parse jobs after worker crashes.

+| `extract_mode` | Что делает | Откуда в UI |
+|----------------|------------|-------------|
+| `heuristic` | Legacy regex-парсер постов | raw job API (не пара) |
+| `llm` | DeepSeek **на каждый** пост (batch) | профиль `kind=llm` → pair flatten |
+| `profile` | Статичные правила `HeuristicProfile` | профиль `kind=heuristic` → pair flatten |

 ### LLM-режим (`extract_mode: llm`)
 
 Для неструктурированных Telegram-постов и Crawl4AI:
 
-- ключ `DEEPSEEK_API_KEY` в `.env` (воркеры `cp-workers` / `cp-workers-web`);
-- Telegram: текст поста → DeepSeek JSON → `IngestEventItem`;
+- ключ `DEEPSEEK_API_KEY` в `.env` (воркеры `cp-workers` / `cp-workers-web`; preview в `ca-api`);
+- Telegram batch: текст → DeepSeek JSON → один или несколько `IngestEventItem` (`workers/llm_extract.py`);
+- опционально `extract_schema`, `instruction`, `required_fields` (post-extract gate поверх `is_event`);
+- **`multi_event`** (opt-in в `llm_profile` / `TelegramSourceConfig`): модель возвращает массив `events`; каждое событие — отдельный ingest. URL: один event → `post.url`; несколько → `post.url#e1`, `#e2`, … (дедуп ЦА по `source_url`);
+- heuristic / profile по-прежнему **1 пост → 1 событие**;
 - Crawl4AI: страница → `LLMExtractionStrategy` (DeepSeek) с fallback на тот же DeepSeek по markdown;
-- в UI «Парсеры»: поле **Извлечение** = LLM DeepSeek.
+- **listener:** для `llm` пока fallback на heuristic (LLM — batch-only by design).
+
+Reusable LLM-профиль в ЦА: `ParserProfile.kind=llm` + JSON `llm_profile` (`contracts/llm_profile.py`). При enqueue flatten → `extract_mode=llm` + schema/instruction/required_fields/`multi_event`.
