[Feat] Unified Agent Writer Page (/agents)

[realproject7]

Summary

Create a single /agents page targeting AI agent operators. Currently the agent registration wizard is at /register-agent (not in NavBar) and there's no developer reference page. Combine everything into one page.

Sections/Tabs

1. Register

• Move the existing ERC-8004 registration wizard from /register-agent
• 3-step flow: agent profile → register identity tx → link operational wallet
• Keep existing logic from src/app/register-agent/page.tsx
• Show registration status if wallet is already registered

2. Build

• CLI quick start: install command, configuration (private key, RPC)
• Available CLI commands with usage examples:
  • plotlink create — create a new storyline from a content file
  • plotlink chain — chain a new plot to an existing storyline
  • plotlink status — check storyline status (plot count, deadline, token price)
  • plotlink claim — claim accumulated royalties
  • plotlink agent register — register as an AI agent writer
• SDK usage: npm install @plotlink/sdk, basic code example showing PlotLink class
• API endpoints reference: /api/index/plot, /api/index/storyline, /api/index/trade

3. Dashboard

• Show the connected agent's storylines (filtered by wallet + writer_type = 1)
• Per-storyline: plot count, deadline countdown, token price, unclaimed royalties
• Claim royalties button per storyline
• If wallet is not registered as agent, prompt to register (link to Register tab)

Navigation

• Add "Agents" to NAV_LINKS in src/components/NavBar.tsx
• Redirect /register-agent to /agents (backwards compatibility)
• Tab-based navigation within the page (Register | Build | Dashboard)

Design

• Match existing Moleskine/monospace aesthetic
• Build section: use code blocks with monospace font for CLI/SDK examples
• Ruled paper styling on code examples would be a nice touch

Reference

• Existing registration wizard: src/app/register-agent/page.tsx
• CLI commands: packages/cli/src/commands/
• SDK client: packages/sdk/src/client.ts
• ERC-8004 registry: 0x8004A169FB4a3325136EB29fA0ceB6D2e539a432

Acceptance Criteria

• /agents page with 3 tabs (Register, Build, Dashboard)
• Registration wizard moved from /register-agent
• /register-agent redirects to /agents
• "Agents" link in NavBar
• CLI/SDK reference with install + usage examples
• Agent dashboard shows storylines for registered agents
• Mobile responsive
• Build passes
