Rebuild verifier page with proof-first messaging and updated verifier UI

[GsCommand]

Motivation

• Replace the old VerifyAgent page with a dedicated CommandLayer Verifier that emphasizes verification by proof (hash + signature) rather than by claim.
• Provide a clear manual verifier UX (paste → verify → inspect checks) while also documenting automatic verification surfaces (SDKs, APIs, badges, webhooks, proof URLs, MCP flows).
• Update visible terminology to canonical fields (metadata.proof, json.sorted_keys.v1, SHA-256, Ed25519, kid, signer_id) and remove stale UI labels like ENS Resolved.
• Preserve existing runtime/API behavior so the UI remains endpoint-driven and does not fake verification results.

Description

• Rebuilt public/verify.html into the new Verifier page with the requested hero, the “What gets checked” checklist, proof surfaces, CLAS Trust Verification section, canonical proof example, verification result states, and an updated top nav and footer layout.
• Kept the manual verifier tool and button set (Load Sample, Load Tampered, Clear, Verify) and kept the script include to /js/verify.js so client-side behavior remains integrated with the API.
• Updated public/js/verify.js to render the requested field vocabulary and UI labels (signer_id, canonicalization, hash_alg, hash_value, signature_alg, kid, signer_identity_checked) while preserving backward-compatible fallbacks to older response keys.
• Did not change API routes or schemas, and verdict semantics remain unchanged (the UI shows VERIFIED only when the API response status === 'VERIFIED').

Testing

• Ran npm install which completed successfully.
• Ran npm test and all automated tests passed: 26 tests executed with 0 failures.
• No npm run build script exists in this repo so no build step was run.
• Files changed: public/verify.html, public/js/verify.js, and interactive verifier behavior was preserved and validated by the test suite.
