Overhaul ERC-8004 agent integration

[realproject7]

Summary

Fixes #583

• CRITICAL fix: Wallet binding deadline reduced from 3600s (1 hour) to 300s (5 minutes) to match contract's max deadline enforcement
• ABI additions: getAgentWallet, unsetAgentWallet, setAgentURI, setMetadata, getMetadata, ownerOf, balanceOf, tokenOfOwnerByIndex, plus URIUpdated and MetadataSet events
• Existing agent detection: On /agents page load, checks both agentIdByWallet() (bound agent wallet) and balanceOf() + tokenOfOwnerByIndex() (NFT owner) to detect registered agents
• Owner vs agent wallet distinction: Owner wallets that hold the AGENT NFT but have a separate bound wallet now correctly see their agent in Dashboard and Management UI
• New AgentManage component: View agent info, update URI metadata, change/unset agent wallet — all with correct 5-minute EIP-712 deadlines
• Registration guard: Existing agents see management UI instead of registration form; tab label changes from "Register" to "Manage"

Test plan

• Verify wallet binding uses 300s deadline (was 3600s)
• Connect an owner wallet that holds an AGENT NFT → should see "Manage" tab with agent info
• Connect a bound agent wallet → should see management UI with "agentWallet" role
• Connect an unregistered wallet → should see registration form
• Test Update URI flow (owner only)
• Test Change Agent Wallet flow (EIP-712 sign + submit)
• Test Unset Agent Wallet button
• Dashboard shows storylines for both owner and agent wallet connections
• Build passes (tsc --noEmit clean)

Verdict: REQUEST CHANGES

Summary

The critical deadline fix is in place, but two owner/external-agent flows are still incorrect. They both break scenarios that issue #583 explicitly calls out.

Findings

• [high] Owner dashboards still lose storylines after unsetAgentWallet() or any transfer-reset to the zero address.
  • File: src/components/AgentDashboard.tsx:55
  • Suggestion: treat 0x0000000000000000000000000000000000000000 as "no bound wallet" and fall back to the owner wallet for storyline lookup so owner-connected dashboards keep working.
• [medium] Existing agents registered from other ERC-8004 apps will not show their current metadata in the new management UI.
  • File: src/components/AgentManage.tsx:93
  • Suggestion: resolve the agentURI by scheme (data:, https://, ipfs://, etc.) and parse the fetched payload, instead of calling JSON.parse() directly on the URI string.

Decision

Request changes. The PR is close, but these two paths still violate the issue requirements for owner dashboards and cross-app existing-agent management.

Verdict: APPROVE

Summary

The follow-up fixes address the two blocking issues from my previous review. Owner dashboards now fall back correctly when the bound wallet is unset, and the management UI can resolve non-JSON ERC-8004 URIs from other apps.

Findings

• No blocking issues found in the updated changes.

Decision

Approve. The PR now satisfies issue #583's critical deadline fix, existing-agent detection, owner-vs-agent wallet handling, and management UI requirements.
