Accessibility Audit Plugin v1.6.1

Reliable full-coverage audit workflow

This patch preserves a cancelled GitHub Action as a cancelled process even when SIGTERM arrives while summaries or outputs are being written.

It includes the v1.6.0 coverage work:

• all 55 active WCAG 2.2 A/AA success criteria accounted for through automated, guided, or human/assistive-technology procedures
• configurable isolated keyboard, forms, focus, interaction, URL, input-value, and live-region journeys
• separate 200% text-resize, 320 CSS-pixel reflow, and text-spacing checks
• native NVDA and VoiceOver evidence workflows
• professional HTML, validated XLSX, JSON, screenshots, and evidence ZIP outputs

Automated results are evidence, not a guarantee of legal or WCAG conformance; criteria requiring human judgment remain explicitly queued for review.
