…gration (Phase 3, #1235) (#1238) Add DagScheduler with tick-based execution loop, command pattern (SchedulerAction), mpsc event channel (TaskEvent/TaskOutcome), task timeout monitoring, cross-task context injection with ContentSanitizer, and stale event guard. Add AgentRouter trait and RuleBasedRouter with 3-step fallback chain (agent_hint, tool keyword matching, first available). Add spawn_for_task() to SubAgentManager with JoinHandle wrapping for orchestration event delivery. Add dependency_context_budget and confirm_before_execute to OrchestrationConfig.
…ration-1238 Resolve conflicts in mod.rs (add both planner and scheduler/router modules), types.rs (merge planner_model/planner_max_tokens with dependency_context_budget/confirm_before_execute), README files, CHANGELOG, docs, and config snapshot.
