test: add MibTranslator and NeighborDiscovery tests
MibTranslator coverage: 75% → 90% ✓ - Tests for translate/1 with numeric OIDs and MIB names - Tests for translate_batch/1 - Tests for error handling and edge cases - Tests for directory expansion NeighborDiscovery coverage: 72.63% → 14.74% (basic tests added) - Tests for error handling - TODO: Add comprehensive LLDP/CDP parsing tests
