refactor(api): integrate NodeRegistry with API Server to eliminate hardcoded node list
This commit resolves technical debt from Story 1-2 by refactoring Node Handler to use NodeRegistry for dynamic node management instead of hardcoded node lists. Key Changes: - Server: Initialize NodeRegistry at startup with builtin nodes (checkout, run) - API Handler: Accept NodeRegistry via dependency injection - getKnownNodes(): Refactored from hardcoded list to registry.List() dynamic loading - Router: Pass NodeRegistry instance from Server to NodeHandlers - Error Handling: Fatal on builtin node registration failure, warn on plugin failures Testing: - New test files: server_noderegistry_test.go, node_handler_noderegistry_test.go, node_handler_getknownnodes_test.go - Coverage: node_handler.go 81-100%, server.go 90.5% - All 7 NodeRegistry tests passing - Backward compatible API response format Documentation: - Updated CHANGELOG.md with Changed/Fixed sections - Marked Story 1-2 technical debt as resolved - Created tech-debt-1-node-handler-registry.md story documentation Benefits: - Adding new nodes no longer requires code changes and redeployment - Unified node management between Agent and API Server - Supports future plugin extensibility Fixes: Technical debt from Story 1-2 (REST API Service Framework) Related: Story 4-1 (Plugin Manager & NodeRegistry) Story: tech-debt-1-node-handler-registry
