Module middleware 

Middleware system for Kit framework

This module provides Laravel 12.x-style middleware support with:

• Global middleware (runs on all routes)
• Route group middleware (shared for a group of routes)
• Per-route middleware (applied to individual routes)

Example

use kit::{async_trait, Middleware, Next, Request, Response, HttpResponse};

pub struct AuthMiddleware;

#[async_trait]
impl Middleware for AuthMiddleware {
    async fn handle(&self, request: Request, next: Next) -> Response {
        if request.header("Authorization").is_none() {
            return Err(HttpResponse::text("Unauthorized").status(401));
        }
        next(request).await
    }
}
