feat(orchestrator): add Discuss Phase and PRD creation workflow (#1124)

* feat(orchestrator): add Discuss Phase and PRD creation workflow

- Introduce Discuss Phase for medium/complex objectives, generating context‑aware options and logging architectural decisions
- Add PRD creation step after discussion, storing the PRD in docs/prd.yaml
- Refactor Phase 1 to pass task clarifications to researchers
- Update Phase 2 planning to include multi‑plan selection for complex tasks and verification with gem‑reviewer
- Enhance Phase 3 execution loop with wave integration checks and conflict filtering

* feat(gem-team): bump version to 1.3.3 and refine description with Discuss Phase and PRD compliance verification
