Bug 47: Toggle Group — Radio-like

WCAG 1.3.1 (Info and Relationships), 4.1.2 (Name, Role, Value) | Button group with no semantic relationship.

Bug: No Grouping Label

Bug: No aria-pressed or Role

Bug: Current Selection Not Indicated

How HAL Fixes This: HAL detects toggle button groups and adds role="group" with aria-label (e.g., "View options" or "Filter tasks"). HAL also adds aria-pressed="true/false" to each button, updating dynamically. For current selection, HAL may add aria-current="page" or aria-pressed="true" on the active button.
