Professionalize homepage + add platform stack, latest-bridged, API & docs

Less talk, more lock-and-mint.

Professionalize homepage + add platform stack, latest-bridged, API & docs — and the bridge got a little sharper for it.

- Homepage: hero + Platform Stack (Binance/Base/Coinbase CDP/Safe brand icons + PayDirect/VNOC/Contrib logos), stats, how-it-works, Latest Bridged feed, features, CTA - API routes: GET /api/tokens, /api/bridges/latest, /api/stats (serve from lib/mock, swap to @assetchain/db once indexed) - Docs: /docs (overview, onboarding, bridging, fees, security/governance, FAQ) + /docs/api (REST reference with examples) - BrandIcons (inline SVG marks), PlatformStack + LatestBridged components, Docs in nav - Logos: real PayDirect/VNOC/Contrib PNGs under public/logos Builds clean (11 routes); all page

Under the hood it's the same promise: lock on BSC, mint 1:1 on Base, hold your own keys. Cross-chain, no drama.
