Dynamic where{Column} methods not resolved on relation chains

[alies-dev]

Problem

Laravel's __call magic on Builder supports dynamic where{Column} methods (e.g., whereEmail('foo') → where('email', '=', 'foo')). These are not resolved when called through a relation.

// ❌ UndefinedMagicMethod
$user->posts()->whereTitle('foo')->get();
$user->posts()->whereSlug('bar')->first();

// ✅ Equivalent explicit call works
$user->posts()->where('title', 'foo')->get();

Priority

Low — explicit where() is the more common pattern, but dynamic where{Column} is used in some codebases.
