feat: ship Redact tool (25th tool) — text-run removal + black-box, complete since cycle 131 but never wired up

redact.js/redact-engine.js were a fully working implementation added
alongside Grayscale but the HTML page was never built, so the tool was
never linked or shipped. Built redact.html, wired it into nav across
every page, added it to tools.html's grid, sitemap.xml, and llms.txt.
Also caught and fixed a stale "23 tools" count on tools.html itself
(missed by prior sweeps of the alternative pages) and bumped the
alternative-page counts from 24 to 25.
