Remove profile system and make custom two-stage selection default

- Remove profiles/ directory with all profile JSON files
- Update install.py to remove profile CLI options and simplify flow
- Make interactive two-stage selection (MCP → Components) the default
- Remove ConfigManager.load_profile() method
- Update documentation to reflect simplified installation process
- Add CLAUDEMdManager for intelligent CLAUDE.md import management
- Components now install to root directory with organized @imports
- Preserve user customizations while managing framework imports

This simplifies the installation experience while providing users
direct control over what gets installed through the intuitive
two-stage selection process.
