refactor: Add tree-style execution flow diagrams to all workflow commands

Added tree-style execution process diagrams using ASCII art (├─, └─, │) to 34 workflow command files across three directories for improved readability and execution flow clarity.

## Changes by Directory

### workflow/ root (17 files)
- lite-plan.md, lite-execute.md, lite-fix.md
- plan.md, execute.md, replan.md
- status.md, review.md, review-fix.md
- review-session-cycle.md, review-module-cycle.md
- session commands (start, complete, resume, list)
- tdd-plan.md, tdd-verify.md, test-cycle-execute.md, test-gen.md, test-fix-gen.md

### workflow/ui-design/ (10 files)
- layout-extract.md, animation-extract.md, style-extract.md
- generate.md, import-from-code.md, codify-style.md
- imitate-auto.md, explore-auto.md
- reference-page-generator.md, design-sync.md

### workflow/tools/ (8 files)
- conflict-resolution.md, task-generate-agent.md, context-gather.md
- tdd-coverage-analysis.md, task-generate-tdd.md
- test-task-generate.md, test-concept-enhanced.md, test-context-gather.md

## Diagram Features
- Input parsing with flag enumeration
- Decision branching with conditional paths
- Phase/step hierarchy with clear nesting
- Mode detection and validation flows
