Function normalize_binding 

pub fn normalize_binding(method: &str, path: &str) -> Result<String, AshError>

Normalize a binding string to canonical form.

Bindings are in the format: METHOD /path

Normalization Rules

• Method is uppercased
• Path must start with /
• Query string is excluded
• Duplicate slashes are collapsed
• Trailing slash is removed (except for root /)

Example

use ash_core::normalize_binding;

let binding = normalize_binding("post", "/api//users/").unwrap();
assert_eq!(binding, "POST /api/users");
