What's new in v0.3.0

⬡ Agent Flow View

• Hexagonal agent nodes with role-based color coding
• Quadratic bezier curved edges with animated particle flow
• Live thought bubbles — active agents show real-time output snippets on the canvas
• Token progress bars under each agent node

📊 Timeline Panel

• Horizontal timeline showing every agent's start/end as a color-coded bar
• Tool call markers overlaid per agent track (web search, LLM, browser)
• Live elapsed time counter for active agents

💰 Token & Cost Tracking

• Per-agent real token counts captured from Anthropic SSE usage events (message_start / message_delta)

🔧 Fixes

• Claude PR review workflow — added actions/checkout step, github_token, and id-token: write permission
