Major architectural improvements to the worker service: - Extracted monolithic WorkerService (~1900 lines) into organized route classes - New HTTP layer with dedicated route handlers: - SessionRoutes: Session lifecycle operations - DataRoutes: Data retrieval endpoints - SearchRoutes: Search/MCP proxy operations - SettingsRoutes: Settings and configuration - ViewerRoutes: Health, UI, and SSE streaming - Added comprehensive README documenting worker architecture - Improved build script to handle worker service compilation - Added context-generator for hook context operations This is Phase 1 of worker refactoring - pure code reorganization with zero functional changes. All existing behavior preserved while improving maintainability and code organization. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
