//! SyncKit Client SDK — end-to-end encrypted cloud sync.
//!
//! All row data is encrypted client-side before leaving the device.
//! The server only ever sees ciphertext.
//!
//! # Quick start
//!
//! ```no_run
//! use synckit_client::{SyncKitClient, SyncKitConfig, ChangeEntry, ChangeOp};
//! use chrono::Utc;
//!
//! # async fn example() -> synckit_client::Result<()> {
//! let client = SyncKitClient::new(SyncKitConfig {
//!     server_url: "https://makenot.work".into(),
//!     api_key: "your-api-key".into(),
//! });
//!
//! // Authenticate
//! let (user_id, app_id) = client.authenticate("user@example.com", "password").await?;
//!
//! // Set up encryption (first device)
//! client.setup_encryption_new("password").await?;
//!
//! // Register this device
//! let device = client.register_device("MacBook Pro", "macos").await?;
//!
//! // Push encrypted data
//! let cursor = client.push(device.id, vec![
//!     ChangeEntry {
//!         table: "tasks".into(),
//!         op: ChangeOp::Insert,
//!         row_id: uuid::Uuid::new_v4().to_string(),
//!         timestamp: Utc::now(),
//!         data: Some(serde_json::json!({"title": "Buy milk"})),
//!     },
//! ]).await?;
//!
//! // Pull and auto-decrypt
//! let (changes, cursor, has_more) = client.pull(device.id, 0).await?;
//! # Ok(())
//! # }
//! ```
