Exclude disabled elements from target-size rule

[Copilot]

Disabled elements cannot be interacted with, so they shouldn't be flagged for failing WCAG 2.5.8 minimum target size (24x24px).

Changes

• src/rules/target-size.ts: Skip elements with disabled attribute in the target-size check
• tests/target-size.ts: Added tests for disabled button, input, select, and textarea elements

// Skip disabled elements (they cannot be interacted with)
if ((target as HTMLElement).hasAttribute("disabled")) {
  continue;
}

Follows existing pattern used in frame-focusable-content.ts and aria-hidden-focus.ts.
