feat: wire quality review into orchestrator handleAgentStopped

When an agent stops, check whether a quality review should run before
auto-completing the task. If shouldRunQualityReview returns run:true,
delegate to runQualityReview (which transitions task to quality_review
and spawns a review agent) instead of calling completeTask directly.

Falls back to completeTask when agentRepository or agentManager are
not injected, or when the task lacks phaseId/initiativeId context.

- Add agentManager optional param to ExecutionOrchestrator constructor
- Extract tryQualityReview() private method to compute branch names and
  repo path before delegating to the quality-review service
- Pass agentManager to ExecutionOrchestrator in container.ts
- Add orchestrator integration tests for the agent:stopped quality hook
