v0.0.2 - Result Builder API

🎨 Result Builder API

This release introduces a Swifty result builder API for constructing Mattermost messages declaratively, making the code more readable and maintainable.

✨ Features

• Result Builder Syntax: Build messages, attachments, and props using a clean, declarative syntax
• Type-Safe Builders: Compile-time safety with Swift 6 strict concurrency
• Fluent API: Chain properties naturally with intuitive naming
• Comprehensive: Covers all message components including text, username, icon, attachments, fields, actions, confirmations, props, and priority

📝 Example

let message = Message {
    "Deployment completed successfully 🚀"
    Username("DeployBot")
    IconEmoji(":rocket:")
    
    Attachment {
        "Good news! Your deployment is complete."
        Color("#36a64f")
        
        Field("Environment", "production")
        Field("Duration", "2m 15s")
        Field("Status", "Success").short()
        
        Action("View Logs", "https://example.com/logs").primary()
        Action("Rollback", "https://example.com/rollback").danger()
    }
}
