fix: Address Copilot review comments on PR #47

This commit resolves all 8 Copilot review comments:

Template fixes (SKILL.md.template):
- Fix #8: Use YAML block scalars for frontmatter to safely handle quotes/newlines
- Fix #2: Add conditional wrapper for command groups section to prevent empty headers

Generator fixes (skill_generator.py):
- Fix #6: Remove unused imports (os, json) and unused decorator_name variable
- Fix #5: Add cli_anything_dir.exists() check before iterdir() with descriptive error
- Fix #7: Add _format_display_name() helper for proper software name formatting
- Fix #4: Change output_path default to use harness_path instead of CWD
- Fix #3: Update regex patterns to handle multi-line decorators and docstrings
