lighty-core 26.5.4

# lighty-core

Core utilities and foundational components for the LightyLauncher ecosystem.

## Overview

**Version**: 26.5.1
**Part of**: [LightyLauncher](https://crates.io/crates/lighty-launcher)

`lighty-core` provides essential building blocks used across all LightyLauncher crates:
- **Application State** - Global app configuration and directory management
- **Download System** - Async file downloads with SHA1 verification
- **Archive Extraction** - ZIP, TAR, and TAR.GZ support with security
- **System Detection** - Cross-platform OS and architecture detection
- **Hash Utilities** - SHA1 verification for files and data
- **Logging Macros** - Unified tracing interface
- **File Macros** - Directory creation utilities

## Quick Start

```toml
[dependencies]
lighty-core = "26.5.1"
```

```rust
use lighty_core::{AppState, system::{OS, ARCHITECTURE}};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    // Initialize application state
    AppState::init("MyLauncher")?;

    println!("Data directory: {}", AppState::data_dir().display());
    println!("Cache directory: {}", AppState::cache_dir().display());
    println!("Running on: {:?} {:?}", OS, ARCHITECTURE);

    Ok(())
}
```

## Features

- **Thread-safe state** - Global AppState with OnceCell
- **Secure extraction** - Path traversal protection, file size limits
- **Smart downloads** - Progress tracking and hash verification
- **Cross-platform** - Windows, macOS, Linux support
- **Zero dependencies** - Minimal external dependencies for core operations
