🚀 Add comprehensive Mailu API tool coverage (v0.2.0)

MASSIVE UPGRADE: Added 27 comprehensive tools covering ALL Mailu API endpoints:

📧 USER ENDPOINTS (5 tools):
- list_users, create_user, get_user, update_user, delete_user

🌐 DOMAIN ENDPOINTS (7 tools):
- list_domains, create_domain, get_domain, update_domain, delete_domain
- generate_dkim_keys, list_domain_users

👥 DOMAIN MANAGER ENDPOINTS (4 tools):
- list_domain_managers, create_domain_manager, get_domain_manager, delete_domain_manager

📍 ALIAS ENDPOINTS (6 tools):
- list_aliases, create_alias, get_alias, update_alias, delete_alias, find_aliases_by_domain

🔄 ALTERNATIVE DOMAIN ENDPOINTS (4 tools):
- list_alternative_domains, create_alternative_domain, get_alternative_domain, delete_alternative_domain

🔗 RELAY ENDPOINTS (5 tools):
- list_relays, create_relay, get_relay, update_relay, delete_relay

✨ FEATURES:
- Complete parameter coverage for all API endpoints
- Comprehensive error handling with try/catch blocks
- Proper request body construction for create/update operations
- All tools support the full Mailu API specification
- Backward compatible with existing basic tools
