Switch is neither perceivable nor operable by assistive technology #550

• Where: switch.rb: role: "switch" on the label with no aria-checked; the checkbox input carries class: "hidden peer" (display: none). Snapshots switch/*.
• Effect: the switch role requires aria-checked; a display: none input leaves the accessibility tree and the tab order, so keyboard users cannot toggle it and the label's focus-visible: classes never apply.
• Fix: render aria-checked and keep it in sync from the controller; sr-only instead of hidden so the input stays focusable; re-record switch/*.

Surfaced by the strict lane of the golden HTML suite (PR #548), which pins what 1.6 renders today — this defect included. Per maintainer decision (2026-09-19) main stays as is: this is addressed on the 2.0 line, and the golden snapshots that pin it are re-recorded there with the diff reviewed.
