feat(vibenet): add Race the Agent validity demo

[haardikk21]

Summary

• add /vibenet/demos/validity/race-the-agent as the second Validity Transactions demo
• deploy a deterministic singleton withdrawal contract, fund it with 2,000,000 VIBE, and gate permissionless 1 VIBE withdrawals on one stable storage condition
• automatically run a page-scoped condition agent that waits 2-10 seconds, opens the condition for roughly 1-2 Vibenet blocks, closes it, and repeats
• compare repeatable ordinary withdrawals with repeatable nonce-free validity transactions pre-submitted against storage == 1
• sample chain state every 200ms, classify EIP-8130 phase outcomes correctly, and retain live history for every attempt in the session
• keep the layout responsive and stable in light/dark modes, including fixed guided-step heights and auto-scrolling state observations

Stack

• Base: feat(vibenet): group validity transaction demos #118
• feat(vibenet): group validity transaction demos #118 is based on feat(vibenet): add Validity demo for conditional inclusion #106

Verification

• npm test (49 files, 331 tests)
• npm run typecheck
• npm run build
• npm run docs:check
• targeted ESLint for the new demo and shared receipt/deployment helpers
• local HTTP 200 for /vibenet/demos/validity and /vibenet/demos/validity/race-the-agent

Notes

• The singleton condition and withdrawal are intentionally permissionless for the demo.
• The condition agent runs only while at least one visitor has the demo page open; it is not an always-on worker.
