Subject: [PATCH] fix(products): hard-block dead composite slugs so
 /products/<slug> 404s
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Zombie slugs (codex-polymarket, codex-kalshi, predexon-kalshi, predexon-limitless, predexon-polymarket) survived past the pre-collapse pm-api-latency split via stale materialize-worker snapshots. The pm-api-latency cohort fix in #725 stops the bench from feeding them, but Upstash keeps the per-slug blobs around for TTL.

Filter them out in buildProviders() so getProvider() returns undefined, the /products/<slug> route falls through to notFound(), the sitemap stops listing them, and related/compare candidates already filter them via the same set in related-providers.ts.

Bumped buildProviders cache key v2→v3 to invalidate the ISR profile list immediately on deploy instead of waiting for the next benchmarks-tag revalidation.
