## 🎯 Feature Highlights

### Type Safety
```rust
// Compile-time type checking
let user: User = response.json().unwrap();

// Type-safe JSON building
let body = json!({"name": "test"});
Request::post(url).json(&body)?;
```

### Chainable Assertions
```rust
Request::get(url)
    .send()?
    .expect_status(200)?
    .expect_json()?
    .assert_field("id", 1)?
    .assert_field("name", "John")?;
```

### JSON Path Queries
```rust
// Nested objects
response.assert_field("user.profile.name", "John")?;

// Array indexing
response.assert_field("items[0].id", 1)?;
```

### Beautiful CLI Output
- Status codes colored by type
- JSON syntax highlighting
- Clean header display
- Request duration tracking

## 🚀 Quick Test Commands

```bash
# Build
cargo build --release

# Run all tests
cargo test

# Run library tests
cargo test --lib

# Run integration tests
cargo test --test integration_tests

# Run with real HTTP endpoints (requires internet)
cargo test --test integration_tests -- --ignored

# Test CLI
./target/release/x-http --help
./target/release/x-http request GET https://httpbin.org/get
./target/release/x-http run --config examples/x-http.toml --name get-example

# Run examples
cargo run --example basic_usage
cargo run --example test_suite
```

## ✨ Key Differentiators

1. **Library + CLI** - Use in tests or standalone
2. **Type-Safe** - Full Rust type safety
3. **Chainable** - Fluent API for assertions
4. **Version Controlled** - Requests live in code/config
5. **No External Dependencies** - No GUI needed
6. **Fast** - Blocking HTTP client, no unnecessary async
7. **Beautiful Output** - Syntax highlighting and colors
8. **Config Files** - Shareable request collections
9. **Interactive Mode** - Quick ad-hoc testing
