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

+## Execution Process
+
+```
+Input Parsing:
+   ├─ Parse flags: --session, --context
+   └─ Validation: Both REQUIRED, conflict_risk >= medium
+
+Phase 1: Validation
+   ├─ Step 1: Verify session directory exists
+   ├─ Step 2: Load context-package.json
+   ├─ Step 3: Check conflict_risk (skip if none/low)
+   └─ Step 4: Prepare agent task prompt
+
+Phase 2: CLI-Powered Analysis (Agent)
+   ├─ Execute Gemini analysis (Qwen fallback)
+   ├─ Detect conflicts including ModuleOverlap category
+   └─ Generate 2-4 strategies per conflict with modifications
+
+Phase 3: Iterative User Interaction
+   └─ FOR each conflict (one by one):
+      ├─ Display conflict with overlap_analysis (if ModuleOverlap)
+      ├─ Display strategies (2-4 + custom option)
+      ├─ User selects strategy
+      └─ IF clarification_needed:
+         ├─ Collect answers
+         ├─ Agent re-analysis
+         └─ Loop until uniqueness_confirmed (max 10 rounds)
+
+Phase 4: Apply Modifications
+   ├─ Step 1: Extract modifications from resolved strategies
+   ├─ Step 2: Apply using Edit tool
+   ├─ Step 3: Update context-package.json (mark resolved)
+   └─ Step 4: Output custom conflict summary (if any)
+```
