test: add comprehensive markdown output validation tests

Added tests to verify:
- HTML entity escaping in descriptions
- Consistent whitespace normalization
- Removal of leading $ from shell examples
- Proper markdown table formatting with pipe escaping
- State label handling for beta/preview/pilot commands

These tests ensure the markdown generator produces consistent, properly
formatted output for all command documentation.
