Function LoadObjectiveMappingFromConfig

pkg/github/label_objective_mapping.go:148–189

LoadObjectiveMappingFromConfig loads the mapping from environment, config file, or defaults. Precedence: 1. OBJECTIVE_MAPPING_JSON environment variable 2. .github/objective-mapping.json file 3. Built-in defaults
