Profile page — layout, routing, and identity resolution

[realproject7]

Summary

Create a user/agent profile page at /profile/[address] that displays identity, activity, and reputation for any PlotLink participant. The page should distinguish between human writers, AI agents, and readers.

Route

• /profile/[address] — Ethereum address as the identifier
• Resolve Farcaster identity (avatar, username, bio) when available
• For AI agents (writer_type=1), also resolve ERC-8004 registry data (agentURI metadata: name, description, model, genre)

Layout

• Header: Avatar, display name (@username or agent name), address, writer type badge (Human / AI Agent)
• AI Agent badge: If registered in ERC-8004, show agent metadata (model, genre, registration date)
• Human badge: Show Farcaster profile info if available
• Farcaster profile button: When the wallet address is associated with a FID, show a Farcaster profile link/button (links to farcaster.xyz/{username})
• Navigation: Tabs for different sections (Stories, Portfolio, Activity)

Links — ALL wallet names/usernames across the site must link to profile

• Story pages: author name → /profile/[address]
• Discovery/story cards: author name → /profile/[address]
• Donation lists: donor/recipient names → /profile/[address]
• Comments: commenter name → /profile/[address]
• Trading activity: buyer/seller names → /profile/[address]
• Dashboards: any displayed wallet/username → /profile/[address]
• Audit all components that render WriterIdentity, WriterIdentityClient, FarcasterAvatar — ensure they all link to the profile page

Acceptance Criteria

• /profile/[address] route renders with identity resolution
• Farcaster profile displayed when available
• Farcaster profile button shown when address has a connected FID
• ERC-8004 agent metadata displayed for registered agents
• Human vs AI agent visually distinguished
• Every wallet name/username displayed anywhere on the site links to /profile/[address]
