Rebuild public API reference into full infrastructure docs page

[GsCommand]

Motivation

• The existing public/api.html was a minimal index and needed to become a developer-facing API reference with the rebuilt site header, Docs dropdown, and footer.
• The page should describe runtime signing, verifier, MCP transport, and website verifier surfaces so developers can integrate verifiable agent workflows.
• Changes must be purely documentation-facing without altering API route behavior, schemas, or deleting files.

Description

• Replaced public/api.html contents with a full API Reference page that uses the same header/nav/docs dropdown and footer style as rebuilt docs pages.
• Added the requested sections: Hero with CTAs, API surface overview cards, Runtime endpoints and supported Trust Verification verbs, Runtime sign and verify examples with expected response shape, MCP endpoints and tools, Website verifier surfaces (with cautious language about /api/verify), request/response conventions, canonical metadata.proof fields, error/status model, security/trust boundaries, developer integration paths, and final CTAs.
• Preserved visual direction and removed stale/non-canonical protocol language in visible copy, explicitly using metadata.proof, json.sorted_keys.v1, SHA-256, Ed25519, vC4WbcNoq2znSCiQ, and runtime.commandlayer.eth.
• Scope limited to a single file change: public/api.html, with no API behavior or schema modifications.

Testing

• Ran npm install which completed successfully using the repository dependencies.
• Ran npm test and all automated tests passed (26/26 passing).
• Ran npm run build which failed because the repository does not define a build script, so no site build artifact was produced.
