What is the current behavior?

Issue Number: #13593

What is the new behavior?

The middleware route exclusion now correctly handles the coexistence of static and dynamic routes:

• Static routes (e.g., /all) are not affected by dynamic route exclusions
• Dynamic routes (e.g., /:id) can be excluded without impacting other routes
• Middleware correctly runs for non-excluded routes while skipping excluded ones

For example, when excluding /:id route:

• Middleware runs for /all endpoint
• Middleware skips /:id endpoint

Does this PR introduce a breaking change?

• Yes
• No

@kamilmysliwiec Can this be merged? 😭

We need to be very careful when making any changes to the middleware exclusion algorithm as they will certainly affect many users of the framework. Might need to wait with this change till the next major release
