Module persistence 

Persistence abstraction for Peat documents

This module provides traits for persisting Peat mesh state across restarts. Platform implementations can use platform-specific storage backends:

• ESP32: NVS (Non-Volatile Storage)
• iOS/macOS: Keychain or UserDefaults
• Android: SharedPreferences or EncryptedSharedPreferences
• Linux: File-based or SQLite

Usage

use peat_btle::persistence::{DocumentStore, MemoryStore};
use peat_btle::document::PeatDocument;
use peat_btle::NodeId;

// Use the in-memory store for testing
let mut store = MemoryStore::new();

// Save a document
let doc = PeatDocument::new(NodeId::new(0x12345678));
store.save(&doc).unwrap();

// Load it back
let loaded = store.load().unwrap();
assert!(loaded.is_some());

Structs
