Move config directory to setup/config and remove unused configurations

- Move config/ to setup/config/ to consolidate installation files
- Delete 3 unused hooks configuration files:
  - hooks-config.json (367 lines of unimplemented hooks config)
  - claude-code-settings-template.json (unused Claude Code hooks template)
  - superclaude-config-template.json (unused SuperClaude config template)
- Keep active configuration files:
  - features.json (component registry)
  - requirements.json (system requirements)
- Update all references to use new CONFIG_DIR path:
  - setup/__init__.py: CONFIG_DIR = SETUP_DIR / "config"
  - setup/operations/install.py: Use CONFIG_DIR import
  - setup/core/validator.py: Use CONFIG_DIR import
- Verify installation functionality works correctly

This consolidates all setup-related configuration in one location
and removes unused configuration cruft from the framework.
