feat(stalk): remove fake genshin stalk

live-probed: /stalk/genshin was NOT real — it just pass-through the raw
SvelteKit __data.json (only nickname/level/nameCardId/profilePicture),
not a full Genshin profile like the Shirokami source (which parses
characters/element/costume/stats via enka-network-api -> get_profile_for_uid).
That proper API is now 404 without an enka token. Removed.

stalk now has 3 real endpoints: github, youtube, twitter.
