refactor: Standardize command naming conventions and remove parent relationships

Updates all command files to use consistent naming without parent field:
- Remove parent field from all command frontmatter
- Standardize name field to use simple names instead of prefixed names
- Fix usage patterns for brainstorm commands to use proper workflow namespace
- Add new medium-project-update.sh script for batch updates
