🔧 Fix critical setup process issues and improve reliability

Major fixes for installation system robustness and version consistency:

**Critical Version Synchronization:**
- Update VERSION file from 4.0.0b1 to 4.0.0 for stable release
- Fix setup/__init__.py to read version from VERSION file dynamically
- Synchronize SuperClaude/__main__.py version reference to 4.0.0
- Establish single source of truth for version management

**NPM Package Naming Resolution:**
- Rename npm package from 'superclaude' to '@superclaude-org/superclaude'
- Resolve naming collision with unrelated GitHub workflow package
- Update package description for clarity and accurate branding
- Enable proper npm organization scoping

**Setup Process Reliability:**
- Fix backup system double extension bug in installer.py
- Improve component discovery error handling with structured logging
- Replace deprecated pkg_resources with modern importlib.resources
- Add comprehensive error handling to installation workflows
- Convert print statements to proper logging throughout codebase

**Error Handling & Logging:**
- Add logger integration to ComponentRegistry and Installer classes
- Enhance exception handling for component instantiation failures
- Improve backup creation error handling with rollback capability
- Standardize error reporting across installation system

**Import System Modernization:**
- Replace deprecated pkg_resources with importlib.resources (Python 3.9+)
- Add robust fallback chain for Python 3.8+ compatibility
- Improve module discovery reliability across different environments

These changes significantly improve installation success rates and eliminate
major pain points preventing successful SuperClaude deployment.
