Improve social link platform detection

Replace brittle href.includes checks with a URL-based detector. Adds hostMatches and detectPlatformFromHref helpers to parse link hostnames (lowercased), handle subdomains, and detect GitHub, Instagram and Discord (discord.gg/discord.com). Uses try/catch and returns 'Unknown' fallback, then uses the detected platform when sending the GA event.
