feat: Add brainstorm artifacts command with unified document structure

- Create dedicated /workflow:brainstorm:artifacts command for topic discussion and decomposition
- Unify document structure between auto.md and artifacts.md commands
- Fix .brainstorming path references to use proper .workflow/WFS-[topic]/ structure
- Add discussion-summary.md and component-analysis.md as shared foundation documents
- Separate synthesis/ folder generation to dedicated synthesis command
- Update auto.md workflow to include Interactive Discussion → Topic Decomposition phases
