feat: Complete Issue #38 TDD8 Cycle 1 - Content command family implementation
Implemented comprehensive content command family for MarkdownMatters CLI following TDD8 methodology and MarkdownMatters specification.
## TDD8 Cycle 1 - Content Commands
### Core Implementation
- Content parser for extracting main content without matter zones
- Content statistics calculator (words, lines, paragraphs, characters)
- CLI commands: `content-get` and `content-stats`
- Full integration with existing markitect CLI
### MarkdownMatters Compliance
- Correctly removes YAML/TOML/JSON frontmatter
- Correctly removes tailmatter blocks (`yaml tailmatter`, `json tailmatter`)
- Preserves contentmatter (MultiMarkdown key-value pairs within content)
- Follows three-zone specification from wiki/MarkdownMatters.md
### Module Structure
```
markitect/content/
├── __init__.py # Module exports
├── parser.py # ContentParser with matter zone removal
├── stats.py # ContentStats data class
└── commands.py # CLI commands implementation
```
### CLI Commands Added
- `markitect content-get --file [path]` - Extract pure content
- `markitect content-stats --file [path]` - Calculate content statistics
### Test Coverage
- 16 comprehensive tests covering all scenarios
- Test fixtures for different document types
- CLI integration tests with Click testing
- Edge case handling (file not found, empty content, etc.)
### Validation Results
- All tests pass (16/16)
- Manual CLI testing confirmed
- Proper matter zone separation validated
- Statistics calculation accuracy verified
## Technical Architecture
### ContentParser Class
- `extract_content()` - Remove frontmatter and tailmatter
- `calculate_stats()` - Generate comprehensive statistics
- `_remove_frontmatter()` - YAML frontmatter removal
- `_remove_tailmatter()` - Tailmatter block removal
### ContentStats Data Class
- word_count, line_count, paragraph_count, character_count
- JSON serialization support via `to_dict()`
## GAMEPLAN Progress
- ✅ TDD8 Cycle 1: Content Commands (COMPLETE)
- 🔄 Next: Cycle 2 - Frontmatter Commands
- Remaining: Contentmatter, Tailmatter command families
This implements the foundation for Issue #38 with 6 remaining cycles planned for complete MarkdownMatters CLI functionality.
