feat: massive Ruflo-inspired upgrade — plugin system, multi-agent swarm, hooks, enhanced memory
New systems (src/plugins/): - Plugin.js: lifecycle hooks (onLoad, onUnload, onConfigChange) + BasePlugin - PluginManager.js: fault-isolated extension point dispatch with metrics - PluginLoader.js: dependency-resolving batch loader with health checks - ExtensionPoints.js: 16 standard extension point names New systems (src/bot/): - hooks.js: HookManager with pre/post tool, pre/post AI, session lifecycle - memory-backend.js: JSONBackend (typed entries + LRU) + InMemoryBackend (ephemeral with TTL) New systems (src/agents/): - Agent.js: typed agents with capabilities, status tracking - Task.js: DAG-compatible tasks with priorities, dependencies, rollback - SwarmCoordinator.js: multi-agent orchestration (simple/hierarchical/swarm topologies) - agents/index.js: 9 agent roles + AgentOrchestrator Bot integration (src/bot/index.js): - 6 new Ruflo-inspired tools: swarm_spawn, swarm_execute, swarm_distribute, swarm_state, swarm_terminate - Plugin system, hook system, swarm initialized in initBot - Pre/post tool hooks wired into tool execution - Ephemeral + persistent memory backends - Agent orchestrator with 9 specialized agent types - Graceful shutdown: all systems cleanup, conversation flush, pidfile release - Return object exposes pluginManager, swarm, hookManager, memBackend, agentOrchestrator, getState This brings Ruflo's multi-agent architecture, plugin extensibility, hook-based lifecycle, and typed memory to zCode.
