feat: Add parallel explore agents to context-gather workflow

- context-gather.md: Add Step 2 with complexity assessment (Low/Medium/High)
  and parallel cli-explore-agent execution (1-4 agents based on complexity)
- context-search-agent.md: Add Track 0 for exploration aggregation with
  exploration_results schema including all_patterns and all_integration_points
- conflict-resolution.md: Consume exploration_results for enhanced conflict
  detection with pre-identified conflict indicators
- task-generate-agent.md: Use exploration critical_files for focus_paths
  and all_patterns/all_integration_points for implementation guidance
