Marketplace discoverability
This release renames the action from "axle — Accessibility Compliance CI" to "axle — a11y / WCAG Accessibility CI" so the Marketplace search for `a11y` finds it.
Why
Searching the GitHub Marketplace for `a11y` returned 9-10 results — all 9 had `a11y` in the title; ours did not. GitHub Marketplace does strict string matching with no synonym expansion. The "Accessibility" word in our title was not enough.
What changed
- `action.yml`: `name` and `description` updated to lead with `a11y / WCAG 2.2 AA`
- README H1 matches the new name; explicit keywords block at top
- Regulatory coverage in description expanded (added Section 508 alongside EAA 2025 / ADA)
Backwards compatible
No behaviour change. `uses: asafamos/axle-action@v1` continues to work — the v1 major tag points at this commit.
