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

+Phase 1: Diagnosis & Root Cause Analysis
+   └─ Decision (confidence-based):
+      ├─ High confidence (specific error) → Direct grep search (5min)
+      ├─ Medium confidence → cli-explore-agent focused search (10-15min)
+      └─ Low confidence (vague) → cli-explore-agent broad search (20min)
+   └─ Hotfix mode: Minimal search (Read suspected file + git blame)
+
+Phase 2: Impact Assessment & Severity Auto-Detection
+   └─ Calculate risk_score → Auto-determine severity
+      ├─ ≥8.0 → critical
+      ├─ ≥5.0 → high
+      ├─ ≥3.0 → medium
+      └─ <3.0 → low
+   └─ Hotfix mode: Skip, assume critical
+
+Phase 3: Fix Planning & Strategy Selection
+   └─ Decision (by risk score):
+      ├─ risk_score ≥5.0 or hotfix → Single best strategy (fastest)
+      └─ risk_score <5.0 → Multiple strategy options for user selection
+
+Phase 4: Verification Strategy
+   └─ Select test scope by risk score
+   └─ Define branch strategy (feature vs hotfix)
+
+Phase 5: User Confirmation
+   └─ Default mode: 3 dimensions (approach, execution, verification)
+   └─ Hotfix mode: 2 dimensions (deploy confirmation, monitoring)
+
+Phase 6: Execution Dispatch
+   ├─ Export Enhanced Task JSON
+   ├─ Dispatch to lite-execute --in-memory
+   └─ Hotfix mode: Generate follow-up tasks
