feat: Add comprehensive quality checker for skills

Phase 2 & 3: Quality assurance before packaging

New module: quality_checker.py
- Enhancement verification (checks for template text, code examples, sections)
- Structure validation (SKILL.md, references/ directory)
- Content quality checks (YAML frontmatter, language tags, "When to Use" section)
- Link validation (internal markdown links)
- Quality scoring system (0-100 score + A-F grade)
- Detailed reporting with errors, warnings, and info messages
- CLI with --verbose and --strict modes

Integration in package_skill.py:
- Automatic quality checks before packaging
- Display quality report with score and grade
- Ask user to confirm if warnings/errors found
- Add --skip-quality-check flag to bypass checks
- Updated help examples

Benefits:
- Catch quality issues before packaging
- Ensure SKILL.md is properly enhanced
- Validate all links work
- Give users confidence in skill quality
- Comprehensive quality reports

Addresses user request: "check some sort of quality check at the end
like is links working, skill is good etc and give report the user"
