Add rule: frame_alignment_requires_dimensions

[kj6dev]

Overview

Warn when using .frame(alignment: .top) without specifying width or height.

frame_alignment_requires_dimensions

Rationale

Frame alignment has no effect without dimensions - likely a mistake.

Example

// ❌ Warning - alignment has no effect
Text("Hello")
    .frame(alignment: .top)

// ✅ Correct - alignment works with dimension
Text("Hello")
    .frame(maxHeight: .infinity, alignment: .top)

Low - straightforward detection, prevents common mistake
