Add rule to detect redundant trait usage

[AronNovak]

This rule detects when a class uses both a trait A and trait B, where trait A already uses trait B (either directly or transitively).

Features

• Detects direct redundancy (class uses A and B, A uses B)
• Detects transitive redundancy (class uses A and C, A uses B, B uses C)
• Configurable via strictRules.noRedundantTraitUse parameter

Example

trait BarTrait {}
trait FooTrait { use BarTrait; }

class MyClass {
    use FooTrait;
    use BarTrait; // Error: redundant, already included via FooTrait
}
