feat: complete Phase 3 enhanced Makefile commands with parameter validation

This commit completes Phase 3 of the multi-provider architecture plan
with enhanced Makefile commands that provide better user experience
and robust parameter validation.

Key Features:
- Parameter validation for all infrastructure commands
- Enhanced provider discovery (infra-providers)
- Environment listing (infra-environments)
- Provider information display (provider-info)
- Robust error handling for invalid parameters
- Check-infra-params validation target

Technical Implementation:
- Added check-infra-params dependency to all infra-* commands
- Parameter validation catches invalid providers and environments
- Provider interface system provides discovery capabilities
- Enhanced help system shows all available commands

Testing Validated:
- Provider discovery: Returns 'libvirt' correctly
- Environment listing: Shows development, staging, production
- Provider info: Displays detailed libvirt configuration
- Error handling: Proper messages for invalid parameters
- Parameter validation: Catches invalid environment/provider combos

Phase 3 Status: COMPLETED
Next: Phase 4 - Hetzner Provider Implementation
