Fix Claude Code marketplace plugin initialization

Replicate complete plugin installation structure for Claude Code Action:

- Create full ~/.claude/plugins/ directory structure
- Check out ai-plugins repo directly to expected location
- Generate all required registry files:
  - config.json (repository configuration)
  - known_marketplaces.json (marketplace source tracking)
  - installed_plugins.json (plugin installation metadata)
  - settings.json (enabled plugins configuration)
- Remove settings parameter from action (auto-discovered from ~/.claude/)
- Add debug output for all generated registry files
- Track git commit SHA for version management

This ensures Claude Code Action recognizes plugins as properly installed
from a GitHub marketplace source.
