Rename scripts for clarity and add Huntarr service

- Renamed all scripts to descriptive names without prefixes:
  • hops.sh → hops (main script)
  • hops_installer_enhanced.sh → install
  • hops_uninstaller_fixed.sh → uninstall
  • hops_service_definitions.sh → services
  • hops_install.sh → setup
  • hops_privileged_setup.sh → privileged-setup
  • hops_user_operations.sh → user-operations
  • hops_service_definitions_improved.sh → services-improved

- Added Huntarr service support:
  • Docker image: ghcr.io/plexguide/huntarr:latest
  • Port: 9705 with /health endpoint
  • Missing media discovery and automation
  • Integrates with *arr stack services
  • Added to installer menu as option 8

- Updated all script references and documentation
- Updated service categories in README and CLAUDE.md
