Architecture

src/
  index.ts              # Worker entry point — parse config, delegate to MCP handler
  server.ts             # createServer() — registers all tools on an McpServer
  config.ts             # HonchoConfig, parseConfig(), createClient()
  types.ts              # ToolContext, result helpers
  tools/
    workspace.ts        # inspect, list, search, metadata
    peers.ts            # CRUD, chat, card, context, representation
    sessions.ts         # CRUD, peers, messages, inspect, context, clone
    conclusions.ts      # list, query, create, delete
    system.ts           # dream, queue status
