Add Proof Flow Composer demo with hybrid live verification

[GsCommand]

Motivation

• Provide a public demo that composes simulated external adapter events (Coinbase, x402) with live CommandLayer runtime signing and live verification into a single trace-linked workflow for exploration and developer UX.

Description

• Added public/proof-flow-composer.html implementing a 4-step UI (Coinbase webhook simulated, x402 payment simulated, runtime live action, VerifyAgent live verification) with a single propagated trace_id, four trace spans, tabs (Final Receipt, Trace, Verification, Trust Boundary), copy buttons, run/reset controls, and explicit simulated vs live labeling.
• Wired the page to call the live runtime at https://runtime.commandlayer.org/summarize/v1.1.0 passing metadata.trace_id, then POST the received runtime receipt to /api/verify with fallback to /api/agents/verifyagent for verification, and render verifier output in the UI.
• Added clearer error reporting in the receipt and verification panels for unreachable/HTTP-failure states, and included a verify cURL snippet and CTAs to /integrations.html, /verify.html, /canonical-receipts.html, and /sdk-records.html.
• Updated public/integrations.html to link to /proof-flow-composer.html and changed favicon references in touched pages from /icon2.png to /favicon.ico to avoid a broken local asset link.

Testing

• Ran npm test which executes node --test tests/*.test.js; test run completed with 54 assertions where 53 passed and 1 failed (failing: tests/api-auth.test.js expecting HTTP 400 but received 503), and all other tests passed.
• Searched for banned identifier with rg -n "erc8211\.merkle\.v1" and found no matches in public/tests/api paths.
• Confirmed /proof-flow-composer.html is linked from public/integrations.html and validated local href targets in the new page (fixed missing favicon reference).
