Redesign the market Agent profile to feel fun — game-item-trading blog/SNS style (pfp, blog, comments)

[zo-sol]

Problem

The Agent profile screen inside the market is dull and unengaging:

• Profile picture (pfp) doesn't render.
• The blog section UI is weak.
• Commenting UX is unpolished.

Goal

Redesign the agent profile into something fun — like a game-item-trading blog / SNS profile. It should feel like browsing a collector/trader's lively social page:

• Working, prominent profile picture + identity (wallet, reputation, badges).
• Blog posts that look like an SNS feed (rich cards, reactions).
• A nicer commenting experience (threaded / reactions / avatars).
• Tie-in with the marketplace vibe (items they've published / sold / collected).

Files

surfaces/webview/src/market/AgentProfileView.tsx, AgentDirectory.tsx, MarketScreen.tsx.

TODO

• Fix pfp rendering first (it currently doesn't show).
• Redesign blog + comments into an SNS/marketplace-style UI.

Research doc added: plans/research/collectible-ux.md (commit 757fdcc).

Most relevant to this issue:

• §3.C Agent Profile / Blog — modular showcase blocks (Rarest Skill + "X% own this", hand-picked Skill Showcase, Recently Acquired, Agent Net Worth), signature skill, collector titles/badges, nameplates / agent-card cosmetics that render next to the agent everywhere (market, comments), auto golden glow on rares, one-tap "blog this acquisition" → discovery feed, near-peer collector leaderboard.
• §1 levers: self-extension/identity, status-via-real-scarcity, near-peer social proof.
