fix: unify Docs dropdown nav and normalize docs index styling

[GsCommand]

Motivation

• Rebuilt pages had inconsistent top navigation where some pages used an old Docs link while others used the new dropdown pattern, causing UX and accessibility regressions.
• The docs index (/docs.html) retained legacy dark/monospace styling in places and needed to match the light ENS/Stripe visual direction used by rebuilt pages.
• Use the /docs/wrap-your-agent.html Docs dropdown as the canonical, clickable pattern so every rebuilt public page has a single predictable nav behavior.

Description

• Standardized the top navigation markup and dropdown behavior to the canonical pattern (<li class="nav-drop"><a href="/docs.html">Docs ▾</a>…</li>) across rebuilt public pages and injected the matching .nav-drop CSS where needed, while preserving hover/focus access and mobile behavior.
• Made the Docs label clickable to /docs.html (instead of a non-clickable button) and preserved the full dropdown menu items: Docs Home, Wrap Your Agent, Production Proof, Runtime, MCP Bridge, Schemas, API Reference, Trust Verification, and Claim / Namespace Activation.
• Updated public/docs.html styling and header/nav to align with the light rebuilt pages and current logo treatment, while keeping Docs Home as the index page content unchanged beyond nav/footer adjustments.
• Files updated: public/index.html, public/protocol.html, public/capabilities.html, public/verify.html, public/sdk-records.html, public/docs.html, public/stack-proof-demo.html, public/claim.html, public/runtime.html, and public/trust-verification.html; no API routes, schemas, or page body content (other than nav/footer consistency) were changed and no files were deleted.

Testing

• Ran npm install which completed successfully with no errors.
• Ran npm test and all automated tests passed (26 tests run, 26 passed, 0 failed).
• Attempted npm run build but no build script exists in package.json, so no build was executed in this repo.
