fix(config): move /discord redirect from Netlify _redirects to vercel.json (#147)

* fix(config): move /discord redirect from Netlify _redirects to vercel.json

The site deploys on Vercel but public/_redirects uses Netlify syntax.
Vercel ignores this file, so /discord returns 404 instead of
redirecting to the Discord invite link.

Move the redirect to vercel.json using the Vercel redirects config
and remove the stale _redirects file.

* fix(config): scope /discord redirect to openclaw.ai host

Add has condition to restrict the redirect to openclaw.ai only,
matching the existing host-scoped routing pattern in vercel.json.
Without this, /discord would redirect on all configured hosts
including trust.openclaw.ai and clawd.bot.
