KOL count: 29 → 25 across marketing/SEO copy

Backend KOL_FEEDS trimmed from 29 to 25 (dead feeds removed). Sync all hardcoded count mentions: - layout.tsx JSON-LD, page.tsx (metric + comparison + copy) - kol/page.tsx, KolPageClient.tsx ("and 26 more" → "and 22 more") - glossary/page.tsx, opengraph-image.tsx - public/llms.txt, llms-full.txt - drop removed KOLs (Dragonfly Capital, Nic Carter) from named lists Bundles other in-flight frontend work already in the working tree.

+/**
+ * Mobile wallet detection and deep-link helpers.
+ *
+ * On mobile browsers (Safari / Chrome) there is no injected `window.ethereum`,
+ * so the `injected()` wagmi connector returns nothing and the user sees
+ * "No wallet provider found". The fix is to detect this state early and offer
+ * deep links that open MetaMask / Trust / Coinbase / OKX and land the user
+ * inside the wallet's in-app browser at the current dApp URL.
+ *
+ * Deep-link patterns used:
+ *   MetaMask  https://metamask.app.link/dapp/<host><path>   (universal link → iOS/Android)
+ *   Trust     https://link.trustwallet.com/open_url?coin_id=60&url=<encoded>
+ *   Coinbase  https://go.cb-wallet.com/dapp?url=<encoded>
+ *   OKX       https://www.okx.com/download?deeplink=okx%3A%2F%2Fmain%2Fdapp%2Fbrowser%3Furl%3D<encoded>
+ *
+ * All links open in a new tab (_blank) so if the user doesn't have the app
+ * installed they land on the wallet's download page without breaking nav.
