refactor: optimize TodoWrite format with hierarchical display across workflow commands

Adopt consistent hierarchical TodoWrite format for better visual clarity:
- Phase-level tasks: "Phase N: Description"
- Sub-tasks: "  → Sub-task description" (indented with arrow)
- Clear parent-child relationships through visual hierarchy
- Task attachment/collapse pattern visualization

Updated commands:
- lite-plan.md (Phase 1-4 examples)
- auto-parallel.md (Phase 0-3 examples)
- tdd-plan.md (Phase 3-5 examples)
- test-fix-gen.md (TodoWrite Pattern with examples)
- explore-auto.md (TodoWrite Pattern)
- imitate-auto.md (TodoWrite Pattern)
- review-session-cycle.md
- review-module-cycle.md

Benefits:
- Visual hierarchy shows task relationships
- Expanded view shows detailed progress
- Collapsed view maintains clean orchestrator-level summary
- Consistent format across all multi-phase workflows

+### Automated Fix Workflow
+After completing a review, use the dashboard to select findings and export them for automated fixing:
+
+```bash
+# Step 1: Complete review (this command)
+/workflow:review-session-cycle
+
+# Step 2: Open dashboard, select findings, and export
+# Dashboard generates: fix-export-{timestamp}.json
+
+# Step 3: Run automated fixes
+/workflow:review-fix .workflow/.reviews/session-{session-id}/fix-export-{timestamp}.json
+```
+
+See `/workflow:review-fix` for automated fixing with smart grouping, parallel execution, and test verification.
+
+### Independent Module Review
+For reviewing specific modules without a workflow session:
+
+```bash
+/workflow:review-module-cycle <path-pattern>
+```
+
+This command provides the same 7-dimension analysis but targets specific files or directories.
