feat: pivot to AI-native task management platform (#232)
Replace the agent framework codebase with a new monorepo structure for an AI-native Linear-like product where agents are first-class citizens. New architecture: - server/ — Go backend (Chi + gorilla/websocket + sqlc) - API server with REST routes for issues, agents, inbox, workspaces - WebSocket hub for real-time updates - Local daemon entry point for agent runtime connection - PostgreSQL migration with 13 tables (issue, agent, inbox, etc.) - WebSocket protocol types for server<->daemon communication - apps/web/ — Next.js 16 frontend - Dashboard layout with sidebar navigation - Route skeleton: inbox, issues, agents, board, settings - packages/ui/ — Preserved shadcn/ui design system (26+ components) - packages/types/ — Full API contract types (Issue, Agent, Workspace, Inbox, Events) - packages/sdk/ — REST ApiClient + WebSocket WSClient - packages/store/ — Zustand stores (issue, agent, inbox, auth) - packages/hooks/ — React hooks (useIssues, useAgents, useInbox, useRealtime) - packages/utils/ — Shared utilities Removed: apps/cli, apps/desktop, apps/mobile, apps/gateway, packages/core, skills/, and all agent-framework code.
