Semantic memory with SQLite and Qdrant for Zeph agent.

## Overview

Provides durable conversation storage via SQLite and semantic retrieval through Qdrant vector search. The `SemanticMemory` orchestrator combines both backends, enabling the agent to recall relevant context from past conversations using embedding similarity.

Includes a document ingestion subsystem for loading, chunking, and storing user documents (text, Markdown, PDF) into Qdrant for RAG workflows.

## Key modules

| Module | Description |
|--------|-------------|
| `sqlite` | SQLite storage for conversations and messages |
| `sqlite::history` | Input history persistence for CLI channel |
| `qdrant` | Qdrant client for vector upsert and search |
| `qdrant_ops` | `QdrantOps` — high-level Qdrant operations |
| `semantic` | `SemanticMemory` — orchestrates SQLite + Qdrant |
| `document` | Document loading, splitting, and ingestion pipeline |
| `document::loader` | `TextLoader` (.txt/.md), `PdfLoader` (feature-gated: `pdf`) |
| `document::splitter` | `TextSplitter` with configurable chunking |
| `document::pipeline` | `IngestionPipeline` — load, split, embed, store via Qdrant |
| `vector_store` | `VectorStore` trait and `VectorPoint` types |
| `embedding_store` | `EmbeddingStore` — high-level embedding CRUD |
| `embeddable` | `Embeddable` trait and `EmbeddingRegistry<T>` — generic Qdrant sync/search for any embeddable type |
| `types` | `ConversationId`, `MessageId`, shared types |
| `error` | `MemoryError` — unified error type |

**Re-exports:** `MemoryError`, `QdrantOps`, `ConversationId`, `MessageId`, `Document`, `DocumentLoader`, `TextLoader`, `TextSplitter`, `IngestionPipeline`, `Chunk`, `SplitterConfig`, `DocumentError`, `DocumentMetadata`, `PdfLoader` (behind `pdf` feature), `Embeddable`, `EmbeddingRegistry`

## Features

| Feature | Description |

| `mock` | In-memory `VectorStore` implementation for testing |
