docs: create comprehensive system analysis report

Replace partial alignment analysis with full SYSTEM_ANALYSIS.md containing:

- Complete deviation analysis (API 60%, UI 80%, Hands 43%, Skills 7%)
- Root cause analysis of gaps
- 5-phase evolution roadmap with clear milestones
- Technical debt inventory
- Acceptance criteria per phase

Key findings:
- Session management API completely missing (0%)
- 4/7 Hands missing TOML configurations
- Workflow editor/delete/create using placeholder alerts
- HandTaskPanel using hardcoded mock data

Updates:
- Archive README updated with clear pointer to new report
- deviation-analysis.md marked as deprecated with comparison table
- knowledge-base README updated to reference SYSTEM_ANALYSIS.md
- Removed partial openfang-alignment-analysis.md
