* 🔥 Remove outdated publishing and release instruction files

Cleaned up repository by removing:
- PUBLISHING.md: Outdated publishing guidelines
- RELEASE_INSTRUCTIONS.md: Old release process documentation

These files are no longer needed as the project has evolved
and the processes have been streamlined or moved elsewhere.

* 🐛 Fix component validation to check metadata file instead of settings.json

Resolves #291 - Validation errors after V4 upgrade

## Changes
- Fixed validation logic to check .superclaude-metadata.json instead of settings.json
- Standardized all component versions to 4.0.4 across the framework
- Fixed agent validation to check for correct filenames (architect vs specialist/engineer)
- Cleaned up metadata file structure for consistency

## Technical Details
The issue was caused by components registering in .superclaude-metadata.json but
validation checking settings.json for component registration. This mismatch caused
false validation errors even though components were properly installed.

## Testing
All components now validate successfully with the corrected logic.
