docs: Enhance TDD command documentation with examples and fix encoding

**Task JSON Examples Added (task-generate-tdd.md)**:
- RED Phase: Complete TEST task JSON with pre_analysis steps
- GREEN Phase: IMPL task JSON with test verification flow
- REFACTOR Phase: Quality-focused refactoring task with safeguards
- All examples include flow_control with pre/post completion steps

**Encoding Fixes (tdd-coverage-analysis.md)**:
- Replace Unicode symbols with ASCII markers
  - ✅ → [PASS]
  - ❌ → [FAIL]
  - ⚠️ → [WARN]
  - → → ->
- Ensure cross-platform compatibility
- Improve readability in all terminals

**Documentation Improvements**:
- Detailed flow_control examples for each TDD phase
- Clear dependency chain examples
- Practical acceptance criteria
- Test framework integration patterns
